+## About
+
+plibsys is a cross-platform system C library with some helpful routines.
+It has zero third-party dependencies and uses only native system calls.
+
+## Features
+
+plibsys gives you:
+
+* Platform independent data types
+* Threads 
+* Mutexes
+* Condition variables
+* Read-write locks
+* System-wide semaphores
+* System-wide shared memory
+* Optimized spinlock
+* Atomic operations
+* Socket support (UDP, TCP, SCTP) with IPv4 and IPv6
+* Hash functions: MD5, SHA-1, SHA-2, SHA-3, GOST (R 34.11-94)
+* Binary trees: BST, red-black, AVL
+* INI file parser
+* High resolution time profiler
+* Files and directories
+* Shared library loading
+* Useful routines for linked lists, strings, hash tables
+* Macros for CPU architecture, OS and compiler detection
+* Macros for variable arguments
+
+To achieve maximum native performance on each platform several implementation models are used:
+
+* Threading models: POSIX, Solaris, OS/2, BeOS, AtheOS, AmigaOS and Win32
+* IPC models: POSIX, System V, OS/2, AmigaOS and Win32
+* Time profiler models: POSIX, Solaris, Mach, OS/2, BeOS, AmigaOS, Win32 and generic
+* Directory iterating models: POSIX, OS/2 and Win32
+* Shared library loading models: POSIX, HP-UX, OS/2, BeOS, AmigaOS and Win32
+* Atomic operations models: sync, C11, DECC, Win32 and simulated
+* Sockets: BSD with Win32 support

+## OpenVMS
+
+This directory contains mainly a build script for OpenVMS.
+
+## Requirements
+
+* OpenVMS 8.4 or later (Alpha or IA64), VAX is not supported
+* DEC CC 6.5 or later
+* DEC CXX 7.1 or later (for tests only)
+
+## Building
+
+Library can be built with 32-bit or 64-bit pointers. By default 64-bit
+pointers are used. Use `32` parameter to switch behaviour.
+
+Test suit is optional and is not built by default. Use `TESTS` parameter to
+enable tests.
+
+There are other build parametes available, plese look inside the
+`build_vms.com` (a DCL-based script) to see the detailed description for
+all of them.
+
+Object library (.OLB) and shareable image (.EXE) are built. An object
+library acts like a widely-known static library, and a shareable image
+acts like a shared library. All libraries and tests are placed inside the
+`[.ALPHA]` or `[.IA64]` directory depending on a host architecture.
+
+Do not forget to define a logical name for a shareable image of the library
+before running programs which use it:
+
+`DEFINE PLIBSYS SYS$SYSROOT:[BUILD_DIR]PLIBSYS.EXE`
+
+You can also place an image into the `SYS$SHARE` directory instead of
+defining a logical name.
+
+Here are some examples of the build commands:
+
+* `@build_vms.com` builds only the libraries (64-bit pointers).
+* `@build_vms.com 32 TESTS` builds libraries (32-bit pointers) and all
+the tests.
+* `@build_vms.com NOLIB RUN_TESTS` only runs already built tests.
+* `@build_vms.com CLEAN` cleans all the files produced during a build.
+
+## More
+
+OpenVMS can mangle long (> 31 characters) symbol names in a compiled object
+to fit the limit. Sometimes it is useful to know the mangled name of a
+symbol. Use the `vms_shorten_symbol.c` program to get a mangled name. See
+details inside.

+$! Command-line options:
+$!
+$!    32            Compile with 32-bit pointers.
+$!    BIGENDIAN     Compile for a big endian host.
+$!    CCQUAL=x      Add "x" to the C compiler qualifiers.
+$!    DEBUG         Build in debug mode.
+$!    CLEAN         Only perform clean after the previous build.
+$!    TESTS=(x)     Build library tests. Comma separated test names or leave
+$!                  empty to build all the tests.
+$!                  Example 1 (curtain tests): TESTS=(pmem,puthread)
+$!                  Example 2 (all tests): TESTS
+$!    RUN_TESTS     Runs all tests.
+$!    NOLIB         Skip library buidling. Useful when you want to rebuild
+$!                  particular tests.

+/* vms_shorten_symbol
+ *
+ * This program provides shortening of long symbols (> 31 characters) using the
+ * same mechanism as the OpenVMS C compiler.  The basic procedure is to compute
+ * an AUTODIN II checksum of the entire symbol, encode the checksum in base32,
+ * and glue together a shortened symbol from the first 23 characters of the
+ * original symbol plus the encoded checksum appended.  The output format is
+ * the same as that of the name mangler database, stored by default in
+ * [.CXX_REPOSITORY]CXX$DEMANGLER_DB.
+ *
+ * To obtain the same result as CC/NAMES=SHORTENED, run like so:
+ *
+ * $ mcr []vms_shorten_symbol "Please_forgive_this_absurdly_long_symbol_name"
+ * PLEASE_FORGIVE_THIS_ABS1ARO4QU$Please_forgive_this_absurdly_long_symbol_name
+ *
+ * To obtain the same result as CC/NAMES=(SHORTENED,AS_IS), pass a non-zero
+ * value as the second argument, like so:
+ *
+ * $ mcr []vms_shorten_symbol "Please_forgive_this_absurdly_long_symbol_name" 1
+ * Please_forgive_this_abs3rv8rnn$Please_forgive_this_absurdly_long_symbol_name

+/**
+ * @file patomic.h
+ * @brief Atomic operations
+ * @author Alexander Saprykin
+ *
+ * Atomic operations can be used to avoid heavy thread synchronization
+ * primitives such as mutexes, semaphores and so on. These operations are
+ * performed atomically and can't be preempted by another thread.
+ *
+ * Lock-free atomic operations require software and hardware support. Usually
+ * lock-free atomic operations are implemented with low-level using assembly
+ * inlines. Some of the compilers provide built-in routines to perform atomic
+ * operations. You can use the p_atomic_is_lock_free() call to check whether
+ * such a support is provided or not.
+ *
+ * If there is no hardware or software support for lock-free atomic operations
+ * then they can be simulated (though in rather slower manner) using a thread
+ * global synchronization primitive (i.e. mutex), but it could block threads
+ * while performing atomic operations on distinct variables from distinct
+ * threads.
+ *
+ * The Windows platform provides all the required lock-free operations in most
+ * cases, so it always has lock-free support.

+/**
+ * @file pcondvariable.h
+ * @brief Condition variable
+ * @author Alexander Saprykin
+ *
+ * A condition variable is an inter-thread synchronization primitive, often
+ * used in the classical 'producers-consumers' concurrent data access models.
+ *
+ * The main idea is to notify waiting thread(s) for some events before they
+ * can enter a critical section. Hence the name of the primitive: a thread
+ * enters the critical section upon an accomplished condition. Compare it with a
+ * mutex where the thread enters the critical section as soon as no one holds a
+ * lock.
+ *
+ * Several threads can be notified at once, but only one of them can enter the
+ * critical section. The order of the threads in that case is implementation
+ * dependent.
+ *
+ * As the thread enters the critical section upon a condition it still requires
+ * a mutex to guard its code against concurrent access from other threads. The
+ * mutex provided in pair with a condition variable will be automatically locked
+ * on the condition, the thread should unlock it explicitly after leaving the
+ * critical section. That mutex is unlocked while waiting for the condition and
+ * should be locked prior calling the condition waiting routine.
+ *
+ * The waiting thread behavior: create a new condition variable with
+ * p_cond_variable_new(), create and lock a mutex before a critical section and
+ * wait for a signal from another thread on this condition variable
+ * using p_cond_variable_wait().
+ *
+ * The signaling thread behavior: upon reaching event time emit a signal with
+ * p_cond_variable_signal() to wake up a single waiting thread or
+ * p_cond_variable_broadcast() to wake up all the waiting threads.
+ *
+ * After emitting the signal only the one thread will get the locked mutex back
+ * to continue executing the critical section.
+ *
+ * It is implementation dependent whether a thread will receive a missed signal
+ * (when a notification from the one thread was emitted prior another thread has
+ * been called for waiting), so do not rely on this behavior.

+/**
+ * @file pcryptohash.h
+ * @brief Cryptographic hash function
+ * @author Alexander Saprykin
+ *
+ * A cryptographic hash function is an algorithm which performs a transformation
+ * of the income data to a hash value.
+ *
+ * One of the main requirements to all of the cryptographic hashing algorithms
+ * is that any (even a considerably small) change in the input data must lead to
+ * notable changes in the result hash value. It is the so called avalanche
+ * effect. It helps to avoid collisions (the same hash value for different
+ * input arrays).
+ *
+ * The cryptographic hash function is designed to be a one-way so you couldn't
+ * revert the output hash value to the input data back. The length of the
+ * resulting hash is a constant value depending on the algorithm being used.
+ *
+ * A cryptographic hash works with the incoming data using fixed length blocks
+ * so it is possible to feed as many data as required.
+ *
+ * The cryptographic hash module supports the following hash functions:
+ * - MD5;
+ * - SHA-1;
+ * - SHA-2/224;
+ * - SHA-2/256;
+ * - SHA-2/384;
+ * - SHA-2/512;
+ * - SHA-3/224;
+ * - SHA-3/256;
+ * - SHA-3/384;
+ * - SHA-3/512;
+ * - GOST (R 34.11-94).
+ *
+ * Use p_crypto_hash_new() to initialize a new hash context with one of the
+ * mentioned above types. Data for hashing can be added in several chunks using
+ * the p_crypto_hash_update() routine. You can add more chunks as long as the
+ * hash context is open.
+ *
+ * The hash context becomes close in two cases: p_crypto_hash_get_string() or
+ * p_crypto_hash_get_digest() was called. After that you can only get a hash in
+ * a hexidemical string or in a raw representation.
+ *
+ * A hashing algorithm couldn't be changed after the context initialization.

+/**
+ * @file pdir.h
+ * @brief Filesystem interface
+ * @author Alexander Saprykin
+ *
+ * A traditional filesystem can be presented as a combination of directories and
+ * files within a defined hierarchy. A directory contains the so called entries:
+ * files and other directories. #PDir allows to iterate through these entries
+ * without reading their contents, thus building a filesystem hierarchy tree.
+ *
+ * Think of this module as an interface to the well-known `dirent` API.
+ *
+ * First you need to open a directory for iterating through its content entries
+ * using p_dir_new(). After that every next entry inside the directory can be
+ * read with the p_dir_get_next_entry() call until it returns NULL (though it's
+ * better to check an error code to be sure no error occurred).
+ *
+ * Also some directory manipulation routines are provided to create, remove and
+ * check existance.

+/**
+ * @file perror.h
+ * @brief Error report system
+ * @author Alexander Saprykin
+ *
+ * An error report system is used to notify a caller about fatal situations
+ * during the library API invocation. Usually the sequence is as following:
+ * @code
+ * PError *error = NULL;
+ * ...
+ *
+ * if (error != NULL) {
+ *         ...
+ *         p_error_free (error);
+ * }
+ * @endcode
+ * Note that you should not initialize a new #PError object before passing the
+ * pointer into an API call. Simply initialize it with zero and check the result
+ * after. Therefore you need to free memory if an error occurred.
+ *
+ * Most operating systems store the last error code of the most system calls in
+ * a thread-specific variable. Moreover, Windows stores the error code of the
+ * last socket related call in a separate variable. Use
+ * p_error_get_last_system() and p_error_set_last_system() to access the last
+ * system error code, p_error_get_last_net() and p_error_set_last_net() to
+ * access the last network error code.

+/**
+ * @file phashtable.h
+ * @brief Hash table
+ * @author Alexander Saprykin
+ *
+ * A hash table is a data structure used to map keys to values. The hash table
+ * consists of several internal slots which hold a list of values. A hash
+ * function is used to compute an index in the array of the slots from a given
+ * key. The hash function itself is fast and it takes a constant time to compute
+ * the internal slot index.
+ *
+ * When the number of pairs in the hash table is small the lookup and insert
+ * (remove) operations are very fast and have average complexity O(1), because
+ * every slot holds almost the only one pair. As the number of internal slots is
+ * fixed, the increasing number of pairs will lead to degraded performance and
+ * the average complexity of the operations can drop to O(N) in the worst case.
+ * This is because the more pairs are inserted the more longer the list of
+ * values is placed in every slot.
+ *
+ * This is a simple hash table implementation which is not intended for heavy
+ * usage (several thousands), see #PTree if you need the best performance on
+ * large data sets. This implementation doesn't support multi-inserts when
+ * several values belong to the same key.
+ *
+ * Note that #PHashTable stores keys and values only as pointers, so you need
+ * to free used memory manually, p_hash_table_free() will not do it in any way.
+ *
+ * Integers (up to 32 bits) can be stored in pointers using #P_POINTER_TO_INT
+ * and #P_INT_TO_POINTER macros.

+/**
+ * @file pinifile.h
+ * @brief INI file parser
+ * @author Alexander Saprykin
+ *
+ * An INI file is usually used for storing configuration information. It
+ * consists of sections: every section starts with a line containing the name in
+ * square brackets (i.e. [section_name]). After that line all the following
+ * parameters will belong to that section until another section begins.
+ *
+ * Each section has a list of key-value pairs. Empty sections are not permitted
+ * (they will be skipped). Every key-value pair is represented with a line in
+ * the `key = value` format. If a section has several values with the same key
+ * the last one will be used. A value is parsed by the first in-order '='
+ * symbol. All the following '=' occurrences belong to the value.
+ *
+ * All symbols after '#' and ';' (even at the line ending) are the comments and
+ * wouldn't be read. If you want to use them in values take the value inside the
+ * "" or '' symbols. A section name line is not allowed to use the comment
+ * symbols after the section name in the square brackets itself.
+ *
+ * Integer values can be written in the usual form.
+ *
+ * Floating point values can be written in any commonly used notation (i.e. with
+ * the decimal point, in the exponential form using the 'e' character). The only
+ * valid decimal point symbol is the '.'. There is no locale dependency on the
+ * decimal point.
+ *
+ * Boolean values can be written in the form of 'true/false' or 'TRUE/FALSE', or
+ * simply '0/1'.
+ *
+ * Any value can be interpreted as a string at any moment. Actually all the
+ * values are stored internally as strings.
+ *
+ * A list of values can be stored between the '{}' symbols separated with
+ * spaces. The list only supports string values, so you should convert them to
+ * numbers manually. The list doesn't support strings with spaces - such strings
+ * will be splitted.
+ *
+ * To parse a file, create #PIniFile with p_ini_file_new() and then parse it
+ * with the p_ini_file_parse() routine.
+ *
+ * #PIniFile handles (skips) UTF-8/16/32 BOM characters (marks).
+ *
+ * Example of the INI file contents:
+ * @code
+ * [numeric_section]
+ * numeric_value_1 = 1234 # One type of the comment
+ * numeric_value_2 = 123  ; Comment is allowed here
+ *
+ * [floating_section]
+ * float_value_1 = 123.3e10
+ * float_value_2 = 123.19
+ *
+ * [boolean_section]
+ * boolean_value_1 = TRUE
+ * boolean_value_2 = 0
+ * boolean_value_3 = false
+ *
+ * [string_section]
+ * string_value_1 = "Test string"
+ * string_value_2 = 'Another test string'
+ *
+ * [list_section]
+ * list_value = {123 val 7654}
+ * @endcode

+/**
+ * @file plibraryloader.h
+ * @brief Shared library loader
+ * @author Alexander Saprykin
+ *
+ * All modern operating systems support dynamic loadable objects. Such objects
+ * are compiled with special flags and can be loaded by other programs and
+ * libraries later at the runtime. These loadable objects often called as the
+ * shared libraries, though some platforms even allow to treat the program
+ * binary as a loadable object, too.
+ *
+ * When the program is linked with a shared library its dependency would be
+ * resolved by the operating system automatically before starting the program.
+ * But in some circumstances you may need to load a shared library object
+ * explicitly (i.e. implementing a plugin subsystem, checking for API
+ * availability).
+ *
+ * All functions and variables which a shared library is exporting are called
+ * symbols. Usually only the exported symbols are available from outside the
+ * shared library. Actually all those symbols represent a library API.
+ *
+ * Use p_library_loader_new() to load a shared library and
+ * p_library_loader_get_symbol() to retrieve a pointer to a symbol within it.
+ * Close the library after usage with p_library_loader_free().
+ *
+ * Please note the following platform specific differences:
+ *
+ * - HP-UX doesn't support loading libraries containing TLS and built with
+ * static TLS model. The same rule applies to any library used as dependency.
+ * HP-UX on 32-bit PA-RISC systems doesn't support reference counting for loaded
+ * libraries when using shl_* family of functions (always removes all library
+ * references on unload).
+ *
+ * - On OpenVMS only shareable images (linked with /SHAREABLE) can be used for
+ * dynamic symbol resolving. Usually they have .EXE extension.
+ *
+ * - BeOS supports dynamic loading for add-ons only. It is also possible to
+ * load the same library several times independently (not like a traditional
+ * shared library).

+/**
+ * @file plist.h
+ * @brief Singly linked list
+ * @author Alexander Saprykin
+ *
+ * A singly linked list is a data structure consists of the nodes which
+ * represent a sequence. Each node contains a data pointer and a pointer to the
+ * next node. Every node has a link only to the next node, hence list is a
+ * singly linked (in a single direction).
+ *
+ * As the singly linked list is a linear collection of the nodes with the
+ * sequential access, it has an O(N) average complexity for appending, removing
+ * and searching operations. Prepending a node takes O(1) constant time. Thus it
+ * is not intended for heavy usage, please refer to #PHashTable or #PTree if you
+ * are working with large data sets.
+ *
+ * Before the first usage you must initialize a #PList variable to NULL. After
+ * that you can use the p_list_append(), p_list_prepend(), p_list_remove() and
+ * p_list_reverse() routines to update that variable:
+ * @code
+ * PList       *list;
+ * ppointer    data;
+ *
+ * list = NULL;
+ * data = my_obj_new ();
+ *
+ * list = p_list_append (list, data);
+ * @endcode
+ * #PList stores only the pointers to the data, so you must free used memory
+ * manually, p_list_free() only frees list's internal memory, not the data it
+ * stores the pointers for. The best approach to free used memory is the
+ * p_list_foreach() routine:
+ * @code
+ * PList    *list;
+ * ...
+ * p_list_foreach (list, (PFunc) my_free_func, my_data);
+ * p_list_free (list);
+ * @endcode
+ * Also you can use #P_INT_TO_POINTER and #P_POINTER_TO_INT macros to store
+ * integers (up to 32-bit) without allocating memory for them:
+ * @code
+ * PList    *list;
+ * pint     a;
+ *
+ * list = p_list_append (list, P_INT_TO_POINTER (12));
+ * a = P_POINTER_TO_INT (list->data);
+ * @endcode
+ * #PList can store several nodes with the same pointer value, but
+ * p_list_remove() will remove only the first matching node.
+ *
+ * If you need to add large amount of nodes at once it is better to prepend them
+ * and then reverse the list.

+/**
+ * @file pmain.h
+ * @brief Library initialization
+ * @author Alexander Saprykin
+ *
+ * Before using the library you must to initialize it properly. Use
+ * p_libsys_init() to initialize the library. Please note that you need to call
+ * it only once, not in every thread. This call is not MT-safe (because it also
+ * initializes the threading subsystem itself), so it is best to place it in the
+ * program's main thread, when the program starts.
+ *
+ * The only difference between p_libsys_init() and p_libsys_init_full() is that
+ * the latter one allows to setup memory management routines before doing any
+ * internal library call. This way you can ensure to use provided memory
+ * management everywhere (even for library initialization).
+ *
+ * When you do not need the library anymore release used resourses with the
+ * p_libsys_shutdown() routine. You should only call it once, too. This call is
+ * not MT-safe (because it also deinitializes the threading subsystem itself),
+ * so it is best to place it in the program's main thread, when the program
+ * finishes.
+ *
+ * It is not recommended to call the initialization and deinitialization
+ * routines on Windows in the DllMain() call because it may require libraries
+ * other than kernel32.dll.

+ * @file pmem.h
+ * @brief Memory management
+ * @author Alexander Saprykin
+ *
+ * Usually the system routines for memory management are used: malloc(),
+ * realloc(), free() and so on. But it is highly encouraged to use a more
+ * general approach: p_malloc(), p_malloc0(), p_realloc() and p_free() family of
+ * memory management routines. It gives you several advantages:
+ * - automatical checking of all input parameters for the NULL values;
+ * - ability to use a custom memory allocator.
+ * You can also mix these two families of calls, but it is not recommended.
+ *
+ * By default p_* routines are mapped to system calls, thus only NULL-checking
+ * is additionally performed. If you want to use the custom memory allocator,
+ * then fill in #PMemVTable structure and pass it to the p_mem_set_vtable(). To
+ * restore system calls back use p_mem_restore_vtable().
+ *
+ * Be careful when using the custom memory allocator: all memory chunks
+ * allocated with the custom allocator must be freed with the same allocator. If
+ * the custom allocator was installed after the library initialization call
+ * p_libsys_init() then you must to restore the original allocator before
+ * calling p_libsys_shutdown().
+ *
+ * Use p_mem_mmap() to allocate system memory using memory mapping and
+ * p_mem_munmap() to release the mapped memory. This type of allocated memory
+ * is not backed physically (does not consume any physical storage) by operating
+ * system. It means that every memory page within the allocated region will be
+ * committed to physical backend only when you first touch it. Until that
+ * untouched pages will be reserved for future usage. It can be useful when
+ * dealing with large memory blocks which should be filled with data on demand,
+ * i.e. custom memory allocator can request a large block first, and then it
+ * allocates chunks of memory within the block upon request.
+ *
+ * @note OS/2 supports non-backed memory pages allocation, but in a specific
+ * way: an exception handler to control access to uncommitted pages must be
+ * allocated on the stack of each thread before using the mapped memory. To
+ * unify the behaviour, on OS/2 all memory mapped allocations are already
+ * committed to the backing storage.

+/**
+ * @file pmutex.h
+ * @brief Mutex routines
+ * @author Alexander Saprykin
+ *
+ * A mutex is a mutual exclusive (hence mutex) synchronization primitive which
+ * allows access to a critical section only to one of the concurrently running
+ * threads. It is used to protected shared data structures from concurrent
+ * modifications which could lead to unpredictable behavior.
+ *
+ * When entering a critical section a thread must call p_mutex_lock() to get a
+ * lock. If another thread is already holding the lock all other threads will
+ * be suspended until the lock is released with p_mutex_unlock(). After
+ * releasing the lock one of the waiting threads is resumed to continue
+ * execution. On most systems it is not specified whether a mutex waiting queue
+ * is fair (FIFO) or not.
+ *
+ * The typical mutex usage:
+ * @code
+ * p_mutex_lock (mutex);
+ *
+ * ... code in critical section ...
+ *
+ * p_mutex_unlock (mutex);
+ * @endcode
+ * You can also think of the mutex as a binary semaphore.
+ *
+ * It is implementation dependent whether recursive locking or non-locked mutex
+ * unlocking is allowed, but such actions can lead to unpredictable behavior.
+ * Do not rely on such behavior in cross-platform applications.
+ *
+ * This is the thread scoped mutex implementation. You could not share this
+ * mutex outside the process adress space, but you can share it between the
+ * threads of the same process.

+ * @file prwlock.h
+ * @brief Read-write lock
+ * @author Alexander Saprykin
+ *
+ * A read-write lock is a synchronization primitive which allows access to a
+ * critical section to not only the one thread, but instead it splits all
+ * threads into the two groups:
+ * - reader threads which perform only the reading operations without any shared
+ * data modifications;
+ * - writer threads which may perform the shared data modifitcations as well as
+ * its reading.
+ *
+ * When there are only the reader threads inside a critical section it is called
+ * a shared lock - actually you do not need any locking mechanism and all the
+ * threads share the lock. In this situation an arbitrary number of reader
+ * threads can perform shared data reading.
+ *
+ * The situation changes when a writer thread requests access to the same
+ * critical section. It will wait until all the current readers finish
+ * executing the critical section before acquiring the lock in exclusive manner:
+ * no one else can access the critical section until the writer finishes with
+ * it. Even another writer thread will have to wait for the lock to be released
+ * by the first writer before entering the critical section.
+ *
+ * To prevent writer startvation usually writers are in favor over readers,
+ * which is actually implementation dependent, though most operating systems try
+ * to follow this rule.
+ *
+ * A read-write lock is usually used when the writing operations are not
+ * performed too frequently, or when the number of reader threads is a way more
+ * than writer ones.
+ *
+ * A reader enters a critical section with p_rwlock_reader_lock() or
+ * p_rwlock_reader_trylock() and exits with p_rwlock_reader_unlock().
+ *
+ * A writer enters the critical section with p_rwlock_writer_lock() or
+ * p_rwlock_writer_trylock() and exits with p_rwlock_writer_unlock().

+/**
+ * @file psemaphore.h
+ * @brief Semaphore routines
+ * @author Alexander Saprykin
+ *
+ * A semaphore is a synchronization primitive which controls access to shared
+ * data from the concurrently running threads. Unlike a mutex (which is a
+ * particular case of a binary semaphore) it allows concurrent access not to
+ * only the one thread.
+ *
+ * The semaphore has a counter which means the number of available resources
+ * (units). Before entering a critical section a thread must perform the so
+ * called P (acquire) operation: if the counter is positive it decrements the
+ * counter by 1 and continues execution; otherwise the thread is suspended until
+ * the counter becomes positive. Before leaving the critical section the thread
+ * must perform the so called V (release) operation: increments the counter by 1
+ * and wakes up a waiting thread from the queue (if any).
+ *
+ * You can think about the semaphore as a resource controller: the P operation
+ * takes one unit, while the V operation gives one unit back. The thread could
+ * not continue execution without taking a resource unit. By setting the initial
+ * semaphore counter value you can control how much concurrent threads can work
+ * with a shared resource.
+ *
+ * This semaphore implementation is process-wide so you can synchronize not only
+ * the threads. But it makes this IPC primitive (actually like any other IPC
+ * primitive, as well) relatively heavy. Consider using a mutex or a spinlock
+ * instead if you do not need to cross a process boundary.
+ *
+ * A process-wide semaphore is identified by its name across the system, thus it
+ * is also called a named semaphore. Use p_semaphore_new() to open the named
+ * semaphore and p_semaphore_free() to close it.
+ *
+ * Please note the following platform specific differences:
+ *
+ * - Windows doesn't own IPC objects (processes own them), which means that a
+ * semaphore will be removed from the system after the last process or thread
+ * closes it (or after terminating all the processes and threads holding open
+ * semaphore).
+ *
+ * - UNIX systems own IPC objects. Because of that UNIX IPC objects can survive
+ * an application crash: an already used semaphore can be opened in a locked
+ * state and an application can fail into a deadlock or an inconsistent state.
+ * This could happen if you have not closed all the open semaphores explicitly
+ * before terminating the application.
+ *
+ * - IRIX allows to open several instances of a semaphore within the single
+ * process, but it will close the object after the first close call from any of
+ * the threads within the process.
+ *
+ * - AmigaOS has process-wide semaphores without actual tracking of counter,
+ * which means that semaphore behaves the same way as recursive mutex.
+ *
+ * - OpenVMS (as of 8.4 release) has declared prototypes for process-wide named
+ * semaphores but the actual implementation is broken.
+ *
+ * - OS/2 lacks support for process-wide named semaphores.
+ *
+ * - Syllable lacks support for process-wide named semaphores.
+ *
+ * - BeOS lacks support for process-wide named semaphores.
+ *
+ * Use the third argument as #P_SEM_ACCESS_CREATE in p_semaphore_new() to reset
+ * a semaphore value while opening it. This argument is ignored on Windows. You
+ * can also take ownership of the semaphore with p_semaphore_take_ownership() to
+ * explicitly remove it from the system after closing.

+ * @file pshm.h
+ * @brief Shared memory
+ * @author Alexander Saprykin
+ *
+ * Shared memory is a memory segment which can be accessed from several threads
+ * or processes. It provides an efficient way to transfer large blocks of data
+ * between processes. It can be used as any other regular memory segment in an
+ * application.
+ *
+ * Shared memory acts like an inter-process communication method. This memory
+ * exchange implementation is process-wide so you can transfer data not only
+ * between the threads. But it makes this IPC method (actually like any other
+ * IPC method, as well) relatively heavy. Consider using other approaches
+ * instead if you do not need to cross the process boundary.
+ *
+ * A shared memory segment doesn't provide any synchronization primitives itself
+ * which means that several processes or threads can concurrently write and read
+ * from it. This can lead to data consistency problems. To avoid such situations
+ * a locking mechanism is provided: use p_shm_lock() before entering a critical
+ * section on the memory segment and p_shm_unlock() when leaving this section.
+ * The locking mechanism is working across the process boundary.
+ *
+ * A process-wide shared memory segment is identified by its name across the
+ * system, thus it is also called a named memory segment. Use p_shm_new() to
+ * open the named shared memory segment and p_shm_free() to close it.
+ *
+ * Please note the following platform specific differences:
+ *
+ * - Windows and OS/2 don't own IPC objects (processes own them), which means
+ * that a shared memory segment will be removed after the last process or thread
+ * detaches (or after terminating all the processes and threads attached to the
+ * segment) it.
+ *
+ * - UNIX systems own IPC objects. Because of that UNIX IPC objects can survive
+ * an application crash: the attached shared memory segment can contain data
+ * from the previous working session. This could happen if you have not detached
+ * from all the shared memory segments explicitly before terminating the
+ * application.
+ *
+ * - HP-UX has limitations due to its MPAS/MGAS features, so you couldn't attach
+ * to the same memory segment twice from the same process.
+ *
+ * - IRIX allows to open several instances of the same buffer within the single
+ * process, but it will close the object after the first close call from any of
+ * the threads within the process.
+ *
+ * - OpenVMS (as of 8.4 release) has broken implementation of process-wide named
+ * semaphores which leads to the broken shared memory also.
+ *
+ * - Syllable lacks support for process-wide named semaphores which leads to the
+ * absence of shared memory.
+ *
+ * - BeOS lacks support for process-wide named semaphores which leads to the
+ * absence of shared memory.
+ *
+ * You can take ownership of the shared memory segment with
+ * p_shm_take_ownership() to explicitly remove it from the system after closing.

+ * @file pshmbuffer.h
+ * @brief Shared memory buffer
+ * @author Alexander Saprykin
+ *
+ * A shared memory buffer works like any other buffer but it is built upon a
+ * shared memory region instead of the process-only address space. Thus it
+ * inherits all the advantages and disadvantages of shared memory behavior. You
+ * should read about #PShm before using this buffer implementation to understand
+ * underlying restrictions.
+ *
+ * The shared memory buffer is process-wide and identified by its name across
+ * the system, thus it can be opened by any process if it knows its name. Use
+ * p_shm_buffer_new() to open the shared memory buffer and p_shm_buffer_free()
+ * to close it.
+ *
+ * All read/write operations are completely thread- and process-safe, which
+ * means that no other synchronization primitive is required, even for inter-
+ * process access. A #PShm locking mechanism is used for access synchronization.
+ *
+ * The buffer is cyclic and non-overridable which means that you wouldn't get
+ * buffer overflow and wouldn't override previously written data until reading
+ * it.
+ *
+ * The read operation checks whether there is any data available and reads it in
+ * case of successful check. After reading the data used space in the buffer is
+ * marked as free and any subsequent write operation may overwrite it. Thus you
+ * couldn't read the same data twice. The read operation is performed with the
+ * p_shm_buffer_read() call.
+ *
+ * The write operation checks whether there is enough free space available and
+ * writes a given memory block only if the buffer has enough free space.
+ * Otherwise no data is written. The write operation is performed with the
+ * p_shm_buffer_write() call.
+ *
+ * Data can be read and written into the buffer only sequentially. There is no
+ * way to access an arbitrary address inside the buffer.
+ *
+ * You can take ownership of the shared memory buffer with
+ * p_shm_buffer_take_ownership() to explicitly remove it from the system after
+ * closing. Please refer to the #PShm description to understand the intention of
+ * this action.

+ * @file psocket.h
+ * @brief Socket implementation
+ * @author Alexander Saprykin
+ *
+ * A socket is a communication primitive usually working over a network. You can
+ * send data to someone's socket by its address and receive data as well through
+ * the same socket. This is one of the most popular and standardizated way for
+ * network communication supported by vast majority of all the modern operating
+ * systems. It also hides all the details of underlying networking protocols and
+ * other layers, providing a unified and transparent approach for communication.
+ *
+ * There are two kinds of socket:
+ * - connection oriented (or stream sockets, i.e. TCP);
+ * - connection-less (or datagram sockets, i.e. UDP).
+ *
+ * Connection oriented sockets work with data in a stream, connection-less
+ * sockets work with data using independent packets (datagrams). The former
+ * guarantees delivery, while the latter doesn't (actually some connection-less
+ * protocols provide delivery quarantee, i.e. SCTP).
+ *
+ * #PSocket supports INET and INET6 address families which specify network
+ * communication addresses used by created sockets: IPv4 and IPv6,
+ * correspondingly. INET6 family is not supported on all platforms, refer to
+ * documentation for a particular target platform.
+ *
+ * #PSocket supports different underlying data transfer protocols: TCP, UDP and
+ * others. Note that not all protocols can be used with any socket type, i.e.
+ * you can use the TCP protocol with a stream socket, but you can't use the UDP
+ * protocol with the stream socket. You can specify #P_SOCKET_PROTOCOL_DEFAULT
+ * protocol when creating a socket and appropriate the best matching socket type
+ * will be selected.
+ *
+ * In a common socket communication case server and client sides are involved.
+ * Depending on whether sockets are connection oriented, there are slightly
+ * different action sequences for data exchanging.
+ *
+ * For connection oriented sockets the server side acts as following:
+ * - creates a socket using p_socket_new();
+ * - binds the socket to a particular local address using p_socket_bind();
+ * - starts to listen incoming connections using p_socket_listen();
+ * - takes an incoming connection from the internal queue using
+ * p_socket_accept().
+ *
+ * The client side acts as following:
+ * - creates a socket using p_socket_new();
+ * - binds the socket to a particular local address using p_socket_bind();
+ * - connects to the server using p_socket_connect().
+ *
+ * After the connection was successfully established, both the sides can send
+ * and receive data from each other using p_socket_send() and
+ * p_socket_receive(). Binding of the client socket is actually optional.
+ *
+ * When using connection-less sockets, all is a bit simpler. There is no server
+ * side or client side - anyone can send and receive data without establishing a
+ * connection. Just create a socket, bind it to a local address and send/receive
+ * data using p_socket_send_to() and p_socket_receive(). You can also call
+ * p_socket_connect() on a connection-less socket to prevent passing the target
+ * address each time when sending data and then use p_socket_send() instead of
+ * p_socket_send_to(). This time binding is required.
+ *
+ * #PSocket can operate in blocking and non-blocking (async) modes. By default
+ * it is in the blocking mode. When using #PSocket in the blocking mode each
+ * non-immediate call on it will block a caller thread until an I/O operation
+ * will be completed. For example, the p_socket_accept() call can wait for an
+ * incoming connection for some time, and calling it on a blocking socket will
+ * prevent the caller thread from further execution until it receives a new
+ * incoming connection. In the non-blocking mode any call will return
+ * immediately and you must check its result. You can set the socket mode using
+ * p_socket_set_blocking().
+ *
+ * #PSocket always puts a socket descriptor (or SOCKET handle on Windows) into
+ * the non-blocking mode and emulates the blocking mode if required. If you need
+ * to perform some hacks and need blocking behavior from the descriptor for some
+ * reason, use p_socket_get_fd() to get an internal socket descriptor (SOCKET
+ * handle on Windows).
+ *
+ * The close-on-exec flag is always set on the socket desciptor. Use
+ * p_socket_get_fd() to overwrite this behavior.
+ *
+ * #PSocket ignores the SIGPIPE signal on UNIX systems if possible. Take it into
+ * account if you want to handle this signal.
+ *
+ * Note that before using the #PSocket API you must call p_libsys_init() in
+ * order to initialize system resources (on UNIX this will do nothing, but on
+ * Windows this routine is required). Usually this routine should be called on a
+ * program's start.
+ *
+ * Here is an example of #PSocket usage:
+ * @code
+ * PSocketAddress *addr;
+ * PSocket	  *sock;
+ *
+ * p_libsys_init ();
+ * ...
+ * if ((addr = p_socket_address_new ("127.0.0.1", 5432)) == NULL) {
+ *	...
+ * }
+ *
+ * if ((sock = p_socket_new (P_SOCKET_FAMILY_INET,
+ *			     P_SOCKET_TYPE_DATAGRAM,
+ *			     P_SOCKET_PROTOCOL_UDP)) == NULL) {
+ *	p_socket_address_free (addr);
+ *	...
+ * }
+ *
+ * if (!p_socket_bind (sock, addr, FALSE)) {
+ *	p_socket_address_free(addr);
+ *	p_socket_free(sock);
+ *	...
+ * }
+ *
+ * ...
+ * p_socket_address_free (addr);
+ * p_socket_close (sock);
+ * p_socket_free (sock);
+ * p_libsys_shutdown ();
+ * @endcode
+ * Here a UDP socket was created, bound to the localhost address and the port
+ * @a 5432. Do not forget to close the socket and free memory after its usage.

+/**
+ * @file psocketaddress.h
+ * @brief Socket address wrapper
+ * @author Alexander Saprykin
+ *
+ * A socket address is usually represented by a network address (IPv4 or IPv6)
+ * and a port number (though some other naming schemes and parameters are
+ * possible).
+ *
+ * Socket address parameters are stored inside a special system (native)
+ * structure in the binary (raw) form. The native structure varies with an
+ * operating system and a network protocol. #PSocketAddress acts like a thin
+ * wrapper around that native address structure and unifies manipulation of
+ * socket address data.
+ *
+ * #PSocketAddress supports IPv4 and IPv6 addresses which consist of an IP
+ * address and a port number. IPv6 support is system dependent and not provided
+ * for all the platforms. Sometimes you may also need to enable IPv6 support in
+ * the system to make it working.
+ *
+ * Convenient methods to create special addresses are provided: for the loopback
+ * interface use p_socket_address_new_loopback(), for the any-address interface
+ * use p_socket_address_new_any().
+ *
+ * If you want to get the underlying native address structure for further usage
+ * in system calls use p_socket_address_to_native(), and
+ * p_socket_address_new_from_native() for a vice versa conversion.

+/**
+ * @file pspinlock.h
+ * @brief Light-weight atomic spinlock
+ * @author Alexander Saprykin
+ *
+ * A spinlock is an inter-thread synchronization primitive based on atomic
+ * operations. It allows to guard a critical section from concurrent access of
+ * multiple threads at once. It is very similar to a mutex in semantics, but
+ * inside it provides a more light-weight and fast locking mechanism without
+ * thread sleeping and undesirable context switching. Thus spinlocks should be
+ * used only for small code sections, otherwise long-time spinning can cause
+ * extensive CPU time waste by waiting threads.
+ *
+ * As the spinlock is based on atomic operations it would have the real meaning
+ * only if an underlying atomic model is lock-free (not simulated using the
+ * mutex). You can check if the atomic model is lock-free with
+ * p_atomic_is_lock_free(). Otherwise usage of spinlocks will be the same as the
+ * ordinary mutex.
+ *
+ * To create a new spinlock primitive the p_spinlock_new() routine should be
+ * called, to delete the unused spinlock primitive use p_spinlock_free().
+ *
+ * Use p_spinlock_lock() or p_spinlock_trylock() to synchronize access at the
+ * beginning of the critical section. Only the one thread is allowed to pass
+ * this call, others will wait for the p_spinlock_unlock() call which marks the
+ * end of the critical section. This way the critical section code is guarded
+ * against concurrent access of multiple threads at once.

+/**
+ * @file pstdarg.h
+ * @brief Variable arguments
+ * @author Jean-Damien Durand
+ *
+ * Functions declared with a variable number of arguments use macros to step
+ * through them.
+ *
+ * The #p_va_list type must be declared in such function, #p_va_start,
+ * #p_va_arg and #p_va_end are used to initialize, to step through and to end
+ * the navigation, respectively.
+ *
+ * A variable number of arguments can be propagated to another function which
+ * accepts a #p_va_list parameter, using #p_va_copy.
+ *
+ * Any use of #p_va_start or #p_va_copy must have a corresponding #p_va_end.
+ *
+ * Using a variable number of parameters requires a known-in-advance contract
+ * between the caller and the callee on the number of parameters and their types.
+ * Note, that this mechanism is a weakly typed: the compiler will always apply
+ * default type promotion, regardless if you explicitely typecast an argument in
+ * the stack, i.e.:
+ * - Integer arguments of types lower than #pint are always promoted to #pint,
+ *   or #puint if #pint is not enough.
+ * - Arguments of type @a float are always promoted to @a double.
+ * - Arrays are always promoted to pointers.
+ *
+ * You need to be very careful when using variable arguments. Improper usage may
+ * lead to program crash. In order to avoid type casting mistakes, consider
+ * using macros for variable arguments with explicit type casting provided below.
+ * Though you still can use #p_va_arg if you know what are you doing.
+ *
+ * Please note, that stdarg.h implementation is not compatible with varargs.h,
+ * and only one of them should be used in a compilation unit. You must be sure
+ * that you don't use varargs.h along with the current implmenetation, otherwise
+ * runtime failures are inevitable.

+ * When the default version of close used on macOS fails with EINTR, the
+ * file descriptor is not in a deterministic state. It may have been closed,
+ * or it may not have been. This makes it impossible to gracefully recover
+ * from the error. If the close is retried after the FD has been closed, the
+ * subsequent close can report EBADF, or worse, it can close an unrelated FD
+ * opened by another thread. If the close is not retried after the FD has been
+ * left open, the FD is leaked. Neither of these are good options.
+ *
+ * macOS provides an alternate version of close, close$NOCANCEL. This
+ * version will never fail with EINTR before the FD is actually closed. With
+ * this version, it is thus safe to call close without checking for EINTR (as
+ * the HANDLE_EINTR macro does) and not risk leaking the FD. In fact, mixing
+ * this verison of close with HANDLE_EINTR is hazardous.
+ *
+ * The $NOCANCEL variants of various system calls are activated by compiling
+ * with __DARWIN_NON_CANCELABLE, which prevents them from being pthread
+ * cancellation points. Rather than taking such a heavy-handed approach, this
+ * file implements an alternative: to use the $NOCANCEL variant of close (thus
+ * preventing it from being a pthread cancellation point) without affecting
+ * any other system calls.
+ *
+ * This file operates by providing a close function with the non-$NOCANCEL
+ * symbol name expected for the compilation environment as set by <unistd.h>
+ * and <sys/cdefs.h> (the DARWIN_ALIAS_C macro). That function calls the
+ * $NOCANCEL variant, which is resolved from libsyscall. By linking with this
+ * version of close prior to the libsyscall version, close's implementation is
+ * overridden.

+ * @author Alexander Saprykin
+ *
+ * #PTimeProfiler acts like a time chronometer: in any moment of time you can
+ * make a time slice to see how much time elapsed since the last slice or timer
+ * start.
+ *
+ * This profiler is useful to gather information about execution time for calls
+ * or parts of the code. It can help to leverage bottle-necks in your code.
+ *
+ * To start using a profiler create a new one with p_time_profiler_new() call
+ * and p_time_profiler_elapsed_usecs() to get elapsed time since the creation.
+ * If you need to reset a profiler use p_time_profiler_reset(). Remove a
+ * profiler with p_time_profiler_free().

+/**
+ * @file ptree.h
+ * @brief Binary tree data structure
+ * @author Alexander Saprykin
+ *
+ * #PTree represents a binary search tree structure for faster lookup than
+ * a plain array or a list. It has average O(logN) time complexity to search
+ * a key-value pair, and O(N) in the worst case (when a tree is degenerated into
+ * the list).
+ *
+ * Currently #PTree supports the following tree types:
+ * - unbalanced binary search tree;
+ * - red-black self-balancing tree;
+ * - AVL self-balancing tree.
+ *
+ * Use p_tree_new(), or its detailed variations like p_tree_new_with_data() and
+ * p_tree_new_full() to create a tree structure. Take attention that a caller
+ * owns the key and the value data passed when inserting new nodes, so you
+ * should manually free the memory after the tree usage. Or you can provide
+ * destroy notification functions for the keys and the values separately.
+ *
+ * New key-value pairs can be inserted with p_tree_insert() and removed with
+ * p_tree_remove().
+ *
+ * Use p_tree_lookup() to find the value by a given key. You can also traverse
+ * the tree in-order with p_tree_foreach().
+ *
+ * Release memory with p_tree_free() or clear a tree with p_tree_clear(). Keys
+ * and values would be destroyed only if the corresponding notification
+ * functions were provided.
+ *
+ * Note: all operations with the tree are non-recursive, only iterative calls
+ * are used.

+ * @file ptypes.h
+ * @brief Types definitions
+ * @author Alexander Saprykin
+ *
+ * Every operating system in pair with a compiler has its own set of data types.
+ * Here you can find unified platform independent data types which guarantee the
+ * same bit-size on every supported platform: #pint8, #pint16, #pint32, #pint64
+ * and their unsigned variants. Also other types are defined for convinience:
+ * #ppointer, #pboolean, #pint, #plong, #pdouble and more.
+ *
+ * Along with the types, length and format modifiers are defined. They can be
+ * used to print and scan data from/to a variable.
+ *
+ * Sometimes it is useful to use an integer variable as a pointer, i.e. to
+ * prevent memory allocation when using hash tables or trees. Use special macros
+ * for that case: #PINT_TO_POINTER, #PPOINTER_TO_INT and their variants. Note
+ * that it will not work with 64-bit data types.
+ *
+ * To check data type limits use P_MIN* and P_MAX* macros.
+ *
+ * If you need to check system endianness compare the P_BYTE_ORDER definition
+ * with the #P_LITTLE_ENDIAN or #P_BIG_ENDIAN macro.
+ *
+ * To convert between the little and big endian byte orders use the Px_TO_LE,
+ * Px_TO_BE, Px_FROM_LE and Px_FROM_BE macros. Macros for the network<->host
+ * byte order conversion are also provided: #p_ntohl, #p_ntohs, #p_ntohs and
+ * #p_ntohl. All the described above macros depend on the target system
+ * endianness. Use PUINTx_SWAP_BYTES to manually swap data types independently
+ * from the endianness.
+ *
+ * You can also find some of the function definitions used within the library.

+/**
+ * @file puthread.h
+ * @brief Multithreading support
+ * @author Alexander Saprykin
+ *
+ * A thread is a system execution unit which is managed independently by the
+ * scheduler of the operating system. It allows to do things in parallel or
+ * concurrently.
+ *
+ * #PUThread provides a convinient way of multithreading support using native
+ * routines to provide the best performance on the target system.
+ *
+ * To create the thread use the p_uthread_create() or p_uthread_create_full()
+ * routines. Joinable threads allow to wait until their execution is finished
+ * before proceeding further. Thus you can synchronize threads' execution within
+ * the main thread.
+ *
+ * A reference counter mechanism is used to keep track of a #PUThread structure.
+ * It means that the structure will be freed automatically when the reference
+ * counter becomes zero. Use p_uthread_ref() to hold the structure and
+ * p_uthread_unref() to decrement the counter back. A running thread holds a
+ * reference to itself structure, so you do not require to hold a reference
+ * to the thread while it is running.
+ *
+ * Priorities (if supported) allow to tune scheduler behavior: threads with
+ * higher priority will be executed more frequently. Be careful that improper
+ * priorities may lead to negative effects when some threads may receive almost
+ * zero execution time.
+ *
+ * Thread priorities are unreliable: not all operating systems respect thread
+ * priorities in favour of process ones. Priorities may be ignored for bound
+ * threads (every thread bound to a kernel light-weight thread as 1:1), other
+ * systems may require administrative privileges to change the thread priority
+ * (i.e. Linux). Windows always respects thread priorities.
+ *
+ * To put the current thread (even if it was not created using the #PUThread
+ * routines) in a sleep state use p_uthread_sleep().
+ *
+ * You can give a hint to the scheduler that the current thread do not need an
+ * execution time with the p_uthread_yield() routine. This is useful when some
+ * of the threads are in an idle state so you do not want to waste a CPU time.
+ * This only tells to the scheduler to skip the current scheduling cycle for the
+ * calling thread, though the scheduler can ingnore it.
+ *
+ * A thread local storage (TLS) is provided. The TLS key's value can be accessed
+ * through a reference key defined as a #PUThreadKey. A TLS reference key is
+ * some sort of a token which has an associated value. But every thread has its
+ * own token value though using the same token object.
+ *
+ * After creating the TLS reference key every thread can use it to access a
+ * local-specific value. Use the p_uthread_local_new() call to create the TLS
+ * reference key and pass it to every thread which needs local-specific values.
+ * You can also provide a destroy notification function which would be called
+ * upon a TLS key removal which is usually performed on the thread exit.
+ *
+ * There are two calls to set a TLS key's value: p_uthread_set_local() and
+ * p_uthread_replace_local(). The only difference is that the former one calls
+ * the provided destroy notification function before replacing the old value.
+ *
+ * Thread names are used on most of operating systems for debugging purposes,
+ * thereby some limitations for long name can be applied and too long names
+ * will be truncated automatically.

+#   PA_PUBLIC_INCLUDES - This contains the list of public PortAudio header
+#       files. These files will be copied into /include paths on Unix'y
+#       systems when "make install" is invoked.
+#   PA_PRIVATE_INCLUDES - This contains the list of header files which
+#       are not part of PortAudio, but are required by the various hostapis.
+#       It is only used by CMake IDE generators (like Visual Studio) to
+#       provide quick-links to useful headers. It has no impact on build
+#       output.
+#   PA_PRIVATE_INCLUDE_PATHS - This contains the list of include paths which
+#       will be passed to the compiler while PortAudio is being built which
+#       are not required by applications using the PortAudio API.
+#   PA_PRIVATE_COMPILE_DEFINITIONS - This contains a list of preprocessor
+#       macro definitions which will be set when compiling PortAudio source
+#       files.
+#   PA_SOURCES - This contains the list of source files which will be built
+#       into the static and shared PortAudio libraries.
+#   PA_NON_UNICODE_SOURCES - This also contains a list of source files which
+#       will be build into the static and shared PortAudio libraries. However,
+#       these sources will not have any unicode compiler definitions added
+#       to them. This list should only contain external source dependencies.
+#   PA_EXTRA_SHARED_SOURCES - Contains a list of extra files which will be
+#       associated only with the shared PortAudio library. This only seems
+#       relevant for Windows shared libraries which require a list of export
+#       symbols.
+# Where other PA_* variables are set, these are almost always only used to
+# preserve the historic SOURCE_GROUP behavior (which again only has an impact
+# on IDE-style generators for visual appearance) or store the output of
+# find_library() calls.

+# PortAudio - portable audio I/O library
+
+PortAudio is a portable audio I/O library designed for cross-platform
+support of audio. It uses either a callback mechanism to request audio 
+processing, or blocking read/write calls to buffer data between the 
+native audio subsystem and the client. Audio can be processed in various 
+formats, including 32 bit floating point, and will be converted to the 
+native format internally.
+
+## Documentation:
+
+* Documentation is available at http://www.portaudio.com/docs/
+* Or at `/doc/html/index.html` after running Doxygen.
+* Also see `src/common/portaudio.h` for the API spec.
+* And see the `examples/` and `test/` directories for many examples of usage. (We suggest `examples/paex_saw.c` for an example.)
+
+For information on compiling programs with PortAudio, please see the
+tutorial at:
+
+  http://portaudio.com/docs/v19-doxydocs/tutorial_start.html
+  
+We have an active mailing list for user and developer discussions.
+Please feel free to join. See http://www.portaudio.com for details.

+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.

+Note: Because PortAudioCpp is now in the main PortAudio SVN repository, having these per-release changelogs probably doesn't make much sense anymore. Perhaps it's better to just note mayor changes by date from now on.
+
+PortAudioCpp v19 revision 16 06/05/22:
+
+	mblaauw:
+	- Added up-to-date MSVC 6.0 projects created by David Moore. Besides MSVC 6.0 users, MSVC 7.0 users may use these projects and automatically convert them to MSVC 7.0 projects.
+	- Changed the code and projects (MSVC 7.1 only) to be up-to-date with PortAudio's new directory structure.
+	- Added equivalents of the PaAsio_GetInputChannelName() and PaAsio_GetOutputChannelName() functions to the AsioDeviceAdapter wrapper-class (missing functions pointed out by David Moore).
+	- Added code to PortAudio's main SVN repository.
+
+PortAudioCpp v19 revision 15 (unknown release date):
+
+	mblaauw:
+	- Changed some exception handling code in HostApi's constructor.
+	- Added accessors to PortAudio PaStream from PortAudioCpp Stream (their absence being pointed out
+	by Tom Jordan).
+	- Fixed a bug/typo in MemFunToCallbackInterfaceAdapter::init() thanks to Fredrik Viklund.
+	- Fixed issue with concrete Stream classes possibly throwing an exception and fixed documentation w.r.t. this.
+	- Moved files to portaudio/binding/cpp/. Made new msvc 7.1 projects to reflect the change and removed msvc 6.0 
+	and 7.0 projects (because I can no longer maintain them myself). Gnu projects will probably need updating.
+
+PortAudioCpp v19 revision 14 03/10/24:
+
+	mblaauw:
+	- Fixed some error handling bugs in Stream and System (pointed out by Tom Jordan).
+	- Updated documentation a little (main page).
+	- Fixed order of members so initializer list was in the right order in 
+	StreamParameters (pointed out by Ludwig Schwardt).
+	- Added new lines at EOF's (as indicated by Ludwig Schwardt).
+
+PortAudioCpp v19 revision 13 03/10/19:
+
+	lschwardt:
+	- Added build files for GNU/Linux.
+	- Fixed bug in Exception where the inherited what() member function (and destructor) had looser 
+	exception specification (namely no exception specification, i.e. could throw anything) than 
+	the std::exception base class's what() member function (which had throw(), i.e. no-throw guarantee).
+	- Changed the iterators so that they have a set of public typedefs instead of deriving the C++ standard 
+	library std::iterator<> struct. G++ 2.95 doesn't support std::exception<> and composition-by-aggregation 
+	is preferred over composition-by-inheritance in this case.
+	- Changed some minor things to avoid G++ warning messages.
+
+	mblaauw:
+	- Renamed this file (/WHATSNEW.txt) to /CHANGELOG.
+	- Renamed /PA_ISSUES.txt to /PA_ISSUES.
+	- Added /INSTALL file with some build info for GNU/Linux and VC6.
+	- Added MSVC 6.0 projects for building PortAudioCpp as a statically or dynamically linkable library.
+	- Moved build files to /build/(gnu/ or vc6/).
+	- Moved Doxygen configuration files to /doc/ and output to /doc/api_reference/.
+	- Added a /doc/README with some info how to generate Doxygen documentation.
+
+PortAudioCpp v19 revision 12 03/09/02:
+
+	mblaauw:
+	- Updated code to reflect changes on V19-devel CVS branch.
+	- Fixed some typos in the documentation.
+
+PortAudioCpp v19 revision 11 03/07/31:
+
+	mblaauw:
+	- Renamed SingleDirecionStreamParameters to DirectionSpecificStreamParameters.
+	- Implemented BlockingStream.
+	- Updated code to reflect recent changes to PortAudio V19-devel.
+	- Fixed a potential memory leak when an exception was thrown in the HostApi 
+	constructor.
+	- Renamed ``Latency'' to ``BufferSize'' in AsioDeviceAdapter.
+	- Updated class documentation.
+
+PortAudioCpp v19 revision 10 03/07/18:
+
+	mblaauw:
+	- SingleDirectionStreamParameters now has a (static) null() method.
+	- StreamParameters uses references for the direction-specific stream parameters 
+	instead of pointers (use null() method (above) instead of NULL).
+	- StreamParameters and SingleDirectionStreamParameters must now be fully specified 
+	and now default values are used (because this was not very useful in general and 
+	only made things more complex).
+	- Updated documentation.
+
+PortAudioCpp v19 revision 09 03/06/25:
+
+	mblaauw:
+	- Changed some things in SingleDirectionStreamParameters to ease it's usage.
+	- Placed all SingleDirectionStreamParameters stuff into a separate file.
+	+ Totally redid the callback stuff, now it's less awkward and supports C++ functions.
+
+PortAudioCpp v19 revision 08 03/06/20:
+
+	mblaauw:
+	- Made deconstructors for Device and HostApi private.
+	+ Added a AsioDeviceWrapper host api specific device extension class.
+	- Refactored Exception into a Exception base class and PaException and PaCppException 
+	derived classes.
+	- Added ASIO specific device info to the devs.cxx example.
+	- Fixed a bug in System::hostApiCount() and System::defaultHostApi().
+	+ Moved Device::null to System::nullDevice.
+	- Fixed some bugs in Device and System.
+
+PortAudioCpp v19 revision 07 03/06/08:
+
+	mblaauw:
+	- Updated some doxy comments.
+	+ Renamed CbXyz to CallbackXyz.
+	+ Renamed all ``configurations'' to ``parameters''.
+	+ Renamed HalfDuplexStreamConfiguration to SingleDirectionStreamConfiguration.
+	- Renamed SingleDirectionStreamParameters::streamParameters() to 
+	SingleDirectionStreamParameters::paSteamParameters.
+	- Added a non-constant version of SingleDirectionStreamParameters::paStreamParameters().
+	- A few improvements to SingleDirectionStreamParameters.
+	- Allowed AutoSystem to be created without initializing the System singleton 
+	(using a ctor flag).
+	- Added a BlockingStream class (not implemented for now).
+	- Fixed many bugs in the implementation of the iterators.
+	- Fixed a bug in Device::operator==().
+	+ Added a C++ version of the patest_sine.c test/example.
+	- Added a ctor for StreamParameters for a default half-duplex stream.
+	- Added SingleDirectionStreamParameters::setDevice() and setNumChannels().
+	- Renamed System::numHostApis() to System::hostApiCount().
+	+ Rewrote the iterators and related classes. They are now fully STL compliant. The System now 
+	has a static array of all HostApis and all Devices. Only the System can create HostApis and 
+	Devices and they are non-copyable now. All HostApis and Devices are now passed by-reference.
+	- Renamed (System::) getVersion() to version() and getVersionText() to versionText().
+	- Renamed (Device::) numXyzChannels() to maxXyzChannels().
+	- Changed some stuff in StreamParameters.
+	+ Added a C++ version of the patest_devs.c test/example.
+
+PortAudioCpp v19 revision 06 03/06/04:
+
+	mblaauw:
+	+ Added this file to the project (roughly, a `+' denotes a major change, a `-' a minor change).
+	- Added System::deviceByIndex(), useful when a Device's index is stored for instance.
+	- Renamed System::hostApiFromTypeId() to System::hostApiByTypeId().
+	- Updated and added some Doxygen documentation.
+	- Made Stream::usedIntputLatency(), Stream::usedOutputLatency() and 
+	Stream::usedSampleRate() throw an paInternalError equivalent exception instead of paBadStreamPtr.
+	- Changed exception handling in Stream::open() functions. They now follow the PA error handling 
+	mechanism better and a couple of bugs regarding ownership of objects were fixed.
+	- Renamed Device::isDefaultXyzDevice() to Device::isSystemDefaultXyzDevice().
+	- Added Device::isHostApiDefaultXyzDevice().
+	- Added StreamConfiguration::unsetFlag().
+	- Removed CUSTOM from SampleDataFormat.
+	- System::hostApiByTypeId() now throws an paInternalError if the type id was out-of-range; this 
+	is a temporary work-around (see comments).
+	- Changed CbInterface to use paCallbackFun() instead of operator()().
+	- Renamed ``object'' to ``instance'' in CbMemFunAdapter.hxx.
+	- Added StreamConfiguration::setXyzHostApiSpecificSampleFormat().
+	- Added StreamConfiguration::isXyzSampleFormatHostApiSpecific().
+	- Changed error handling in System::terminate(), it can now throw an Exception.
+	- Added error handling in System::defaultHostApi().
+	- Added error handling in System::hostApisEnd().
+	- Changed some (but probably not all) C casts to C++ casts to avoid confusion with a 
+	certain Python person.
+	- Renamed RaiiSystem to AutoSystem (class and file) as this is a come common convention.
+	- Renamed System::numDevices() to System::deviceCount() to be more compatible with PortAudio 
+	(although PortAudio uses Pa_CountDevices() instead, see comment).
+	- Renamed HostApi::numDevices() to HostApi::deviceCount().
+	- Changed INC_ to INCLUDED_ in the header multiple include guards.
+	- Changed the order of functions in the StreamConfiguration class' header.
+	- Written some more info in PortAudioCpp.hxx (Doxygen).

+Installation Instructions

+
+Basic Installation
+==================
+
+   Briefly, the shell command `./configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved.  Use GNU `make'
+instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation.  Until the limitation is lifted, you can use
+this workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CPP         C preprocessor
+  CXXCPP      C++ preprocessor

+///	<h1>PortAudioCpp - A Native C++ Binding of PortAudio V19</h1>
+/// <h2>PortAudio</h2>
+/// <p>
+///   PortAudio is a portable and mature C API for accessing audio hardware. It offers both callback-based and blocking 
+///   style input and output, deals with sample data format conversions, dithering and much more. There are a large number 
+///   of implementations available for various platforms including Windows MME, Windows DirectX, Windows and MacOS (Classic) 
+///   ASIO, MacOS Classic SoundManager, MacOS X CoreAudio, OSS (Linux), Linux ALSA, JACK (MacOS X and Linux) and SGI Irix 
+///   AL. Note that, currently not all of these implementations are equally complete or up-to-date (as PortAudio V19 is 
+///   still in development). Because PortAudio has a C API, it can easily be called from a variety of other programming 
+///   languages.
+/// </p>
+/// <h2>PortAudioCpp</h2>
+/// <p>
+///   Although, it is possible to use PortAudio's C API from within a C++ program, this is usually a little awkward 
+///   as procedural and object-oriented paradigms need to be mixed. PortAudioCpp aims to resolve this by encapsulating 
+///   PortAudio's C API to form an equivalent object-oriented C++ API. It provides a more natural integration of PortAudio 
+///   into C++ programs as well as a more structured interface. PortAudio's concepts were preserved as much as possible and 
+///   no additional features were added except for some `convenience methods'.
+/// </p>
+/// <p>
+///   PortAudioCpp's main features are:
+///   <ul>
+///     <li>Structured object model.</li>
+///     <li>C++ exception handling instead of C-style error return codes.</li>
+///     <li>Handling of callbacks using free functions (C and C++), static functions, member functions or instances of classes 
+///     derived from a given interface.</li>
+///     <li>STL compliant iterators to host APIs and devices.</li>
+///     <li>Some additional convenience functions to more easily set up and use PortAudio.</li>
+///   </ul>
+/// </p>
+/// <p>
+///   PortAudioCpp requires a recent version of the PortAudio V19 source code. This can be obtained from CVS or as a snapshot 
+///   from the website. The examples also require the ASIO 2 SDK which can be obtained from the Steinberg website. Alternatively, the 
+///   examples can easily be modified to compile without needing ASIO.
+/// </p>
+/// <p>
+///   Supported platforms:
+///   <ul>
+///     <li>Microsoft Visual C++ 6.0, 7.0 (.NET 2002) and 7.1 (.NET 2003).</li>
+///     <li>GNU G++ 2.95 and G++ 3.3.</li>
+///   </ul>
+///   Other platforms should be easily supported as PortAudioCpp is platform-independent and (reasonably) C++ standard compliant.
+/// </p>
+/// <p>
+///   This documentation mainly provides information specific to PortAudioCpp. For a more complete explanation of all of the 
+///   concepts used, please consult the PortAudio documentation.
+/// </p>
+/// <p>
+///   PortAudioCpp was developed by Merlijn Blaauw with many great suggestions and help from Ross Bencina. Ludwig Schwardt provided 
+///   GNU/Linux build files and checked G++ compatibility. PortAudioCpp may be used under the same licensing, conditions and 
+///   warranty as PortAudio. See <a href="http://www.portaudio.com/license.html">the PortAudio license</a> for more details.

+/** 
+@page java_binding JPortAudio Java Binding
+@ingroup jportaudio
+
+<i>Note: this page has not been reviewed, and may contain errors.</i>
+
+@section java_draft DRAFT - IN PROGRESS
+
+9/4/12 JPortAudio is very new and should be considered an "alpha" release.
+The building of JPortAudio will eventually be integrated into the Makefile as an optional build.
+
+Currently JPortAudio is only supported for Windows and Macintosh. Please contact us if you want to help with porting Linux.
+
+For reference documentation of the JPortAudio API see: com.portaudio.PortAudio
+
+For an example see: PlaySine.java
+
+@section java_comp_windows Building JPortAudio on Windows
+
+Build the Java code using the Eclipse project in "jportaudio". Export as "jportaudio.jar".
+
+If you modify the JNI API then you will need to regenerate the JNI .h files using:
+
+@code
+cd bindings/java/scripts
+make_header.bat
+@endcode
+
+Build the JNI DLL using the Visual Studio 2010 solution in "java/c/build/vs2010/PortAudioJNI".
+
+@section java_use_windows Using JPortAudio on Windows
+
+Put the "jportaudio.jar" in the classpath for your application.
+Place the following libraries where they can be found, typically in the same folder as your application.
+
+- portaudio_x86.dll
+- portaudio_x64.dll
+- jportaudio_x86.dll
+- jportaudio_x64.dll
+
+@section java_comp_max Building JPortAudio on Mac
+
+These are notes from building JPortAudio on a Mac with 10.6.8 and XCode 4.
+
+I created a target of type 'C' library.
+
+I added the regular PortAudio frameworks plus the JavaVM framework.
+
+I modified com_portaudio_PortAudio.h and com_portaudio_BlockingStream.h so that jni.h could found.
+
+@code
+#if defined(__APPLE__)
+#include <JavaVM/jni.h>
+#else
+#include <jni.h>
+#endif
+@endcode
+
+This is bad because those header files are autogenerated and will be overwritten.
+We need a better solution for this.
+
+I had trouble finding the "libjportaudio.jnilib". So I added a Build Phase that copied the library to "/Users/phil/Library/Java/Extensions".
+
+On the Mac we can create a universal library for both 32 and 64-bit JVMs. So in the JAR file I will open "jportaudio" on Apple. ON WIndows I will continue to open "jportaudio_x64" and "jportaudio_x86".

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+/** @page api_overview PortAudio API Overview
+
+This page provides a top-down overview of the entire PortAudio API. It describes how all of the PortAudio data types and functions fit together. It provides links to the documentation for each function and data type. You can find all of the detailed documentation for each API function and data type on the portaudio.h page.
+
+@section introduction Introduction
+
+PortAudio provides a uniform application programming interface (API) across all supported platforms. You can think of the PortAudio library as a wrapper that converts calls to the PortAudio API into calls to platform-specific native audio APIs. Operating systems often offer more than one native audio API and some APIs (such as JACK) may be available on multiple target operating systems. PortAudio supports all the major native audio APIs on each supported platform. The diagram below illustrates the relationship between your application, PortAudio, and the supported native audio APIs:
+
+@image html portaudio-external-architecture-diagram.png
+
+PortAudio provides a uniform interface to native audio APIs. However, it doesn't always provide totally uniform functionality. There are cases where PortAudio is limited by the capabilities of the underlying native audio API. For example, PortAudio doesn't provide sample rate conversion if you request a sample rate that is not supported by the native audio API. Another example is that the ASIO SDK only allows one device to be open at a time, so PortAudio/ASIO doesn't currently support opening multiple ASIO devices simultaneously.
+
+@section key_abstractions Key abstractions: Host APIs, Devices and Streams
+
+The PortAudio processing model includes three main abstractions: <i>Host APIs</i>, audio <i>Devices</i> and audio <i>Streams</i>.
+
+Host APIs represent platform-specific native audio APIs. Some examples of Host APIs are Core Audio on Mac OS, WMME and DirectSound on Windows and OSS and ALSA on Linux. The diagram in the previous section shows many of the supported native APIs. Sometimes it's useful to know which Host APIs you're dealing with, but it is easy to use PortAudio without ever interacting directly with the Host API abstraction.
+
+Devices represent individual hardware audio interfaces or audio ports on the host platform. Devices have names and certain capabilities such as supported sample rates and the number of supported input and output channels. PortAudio provides functions to enumerate available Devices and to query for Device capabilities.
+
+Streams manage active audio input and output from and to Devices. Streams may be half duplex (input or output) or full duplex (simultaneous input and output). Streams operate at a specific sample rate with particular sample formats, buffer sizes and internal buffering latencies. You specify these parameters when you open the Stream. Audio data is communicated between a Stream and your application via a user provided asynchronous callback function or by invoking synchronous read and write functions.
+
+PortAudio supports audio input and output in a variety of sample formats: 8, 16, 24 and 32 bit integer formats and 32 bit floating point, irrespective of the formats supported by the native audio API.  PortAudio also supports multichannel buffers in both interleaved and non-interleaved (separate buffer per channel) formats and automatically performs conversion when necessary. If requested, PortAudio can clamp out-of range samples and/or dither to a native format.
+
+The PortAudio API offers the following functionality:
+- Initialize and terminate the library
+- Enumerate available Host APIs
+- Enumerate available Devices either globally, or within each Host API
+- Discover default or recommended Devices and Device settings
+- Discover Device capabilities such as supported audio data formats and sample rates
+- Create and control audio Streams to acquire audio from and output audio to Devices
+- Provide Stream timing information to support synchronising audio with other parts of your application
+- Retrieve version and error information.
+
+These functions are described in more detail below.
+
+
+@section top_level_functions Initialization, termination and utility functions
+
+The PortAudio library must be initialized before it can be used and terminated to clean up afterwards. You initialize PortAudio by calling Pa_Initialize() and clean up by calling Pa_Terminate(). 
+
+You can query PortAudio for version information using Pa_GetVersion() to get a numeric version number and Pa_GetVersionText() to get a string.
+
+The size in bytes of the various sample formats represented by the @ref PaSampleFormat enumeration can be obtained using Pa_GetSampleSize().
+
+Pa_Sleep() sleeps for a specified number of milliseconds. This isn't intended for use in production systems; it's provided only as a simple portable way to implement tests and examples where the main thread sleeps while audio is acquired or played by an asynchronous callback function.
+
+@section host_apis Host APIs
+
+A Host API acts as a top-level grouping for all of the Devices offered by a single native platform audio API. Each Host API has a unique type identifier, a name, zero or more Devices, and nominated default input and output Devices. 
+
+Host APIs are usually referenced by index: an integer of type @ref PaHostApiIndex that ranges between zero and Pa_GetHostApiCount() - 1. You can enumerate all available Host APIs by counting across this range.
+
+You can retrieve the index of the default Host API by calling Pa_GetDefaultHostApi().
+
+Information about a Host API, such as it's name and default devices, is stored in a @ref PaHostApiInfo structure. You can retrieve a pointer to a particular Host API's @ref PaHostApiInfo structure by calling Pa_GetHostApiInfo() with the Host API's index as a parameter.
+
+Most PortAudio functions reference Host APIs by @ref PaHostApiIndex indices. Each Host API also has a unique type identifier defined in the @ref PaHostApiTypeId enumeration.
+You can call Pa_HostApiTypeIdToHostApiIndex() to retrieve the current @ref PaHostApiIndex for a particular @ref PaHostApiTypeId.
+
+@section devices Devices
+
+A Device represents an audio endpoint provided by a particular native audio API. This usually corresponds to a specific input or output port on a hardware audio interface, or to the interface as a whole. Each Host API operates independently, so a single physical audio port may be addressable via different Devices exposed by different Host APIs.
+
+A Device has a name, is associated with a Host API, and has a maximum number of supported input and output channels. PortAudio provides recommended default latency values and a default sample rate for each Device. To obtain more detailed information about device capabilities you can call Pa_IsFormatSupported() to query whether it is possible to open a Stream using particular Devices, parameters and sample rate.
+
+Although each Device conceptually belongs to a specific Host API, most PortAudio functions and data structures refer to Devices using a global, Host API-independent index of type @ref PaDeviceIndex &ndash; an integer of that ranges between zero and Pa_GetDeviceCount() - 1. The reasons for this are partly historical but it also makes it easy for applications to ignore the Host API abstraction and just work with Devices and Streams.
+
+If you want to enumerate Devices belonging to a particular Host API you can count between 0 and PaHostApiInfo::deviceCount - 1. You can convert this Host API-specific index value to a global @ref PaDeviceIndex value by calling Pa_HostApiDeviceIndexToDeviceIndex().
+
+Information about a Device is stored in a @ref PaDeviceInfo structure. You can retrieve a pointer to a Devices's @ref PaDeviceInfo structure by calling Pa_GetDeviceInfo() with the Device's index as a parameter.
+
+You can retrieve the indices of the global default input and output devices using Pa_GetDefaultInputDevice() and Pa_GetDefaultOutputDevice(). Default Devices for each Host API are stored in the Host API's @ref PaHostApiInfo structures.
+
+For an example of enumerating devices and printing information about their capabilities see the pa_devs.c program in the test directory of the PortAudio distribution.
+
+@section streams Streams
+
+A Stream represents an active flow of audio data between your application and one or more audio Devices. A Stream operates at a specific sample rate with specific sample formats and buffer sizes.
+
+@subsection io_methods I/O Methods: callback and read/write
+
+PortAudio offers two methods for communicating audio data between an open Stream and your Application: (1) an asynchronous callback interface, where PortAudio calls a user defined callback function when new audio data is available or required, and (2) synchronous read and write functions which can be used in a blocking or non-blocking manner. You choose between the two methods when you open a Stream. The two methods are discussed in more detail below.
+
+@subsection opening_and_closing_streams Opening and Closing Streams
+
+You call Pa_OpenStream() to open a Stream, specifying the Device(s) to use, the number of input and output channels, sample formats, suggested latency values and flags that control dithering, clipping and overflow handling. You specify many of these parameters in two PaStreamParameters structures, one for input and one for output. If you're using the callback I/O method you also pass a callback buffer size, callback function pointer and user data pointer. 
+
+Devices may be full duplex (supporting simultaneous input and output) or half duplex (supporting input or output) &ndash; usually this reflects the structure of the underlying native audio API. When opening a Stream you can specify one full duplex Device for both input and output, or two different Devices for input and output. Some Host APIs only support full-duplex operation with a full-duplex device (e.g. ASIO) but most are able to aggregate two half duplex devices into a full duplex Stream. PortAudio requires that all devices specified in a call to Pa_OpenStream() belong to the same Host API.
+
+A successful call to Pa_OpenStream() creates a pointer to a @ref PaStream &ndash; an opaque handle representing the open Stream. All PortAudio API functions that operate on open Streams take a pointer to a @ref PaStream as their first parameter.
+
+PortAudio also provides Pa_OpenDefaultStream() &ndash; a simpler alternative to Pa_OpenStream() which you can use when you want to open the default audio Device(s) with default latency parameters.
+
+You call Pa_CloseStream() to close a Stream when you've finished using it.
+
+@subsection starting_and_stopping_streams Starting and Stopping Streams
+
+Newly opened Streams are initially stopped. You call Pa_StartStream() to start a Stream. You can stop a running Stream using Pa_StopStream() or Pa_AbortStream() (the Stop function plays out all internally queued audio data, while Abort tries to stop as quickly as possible). An open Stream can be started and stopped multiple times. You can call Pa_IsStreamStopped() to query whether a Stream is running or stopped.
+
+By calling Pa_SetStreamFinishedCallback() it is possible to register a special @ref PaStreamFinishedCallback that will be called when the Stream has completed playing any internally queued buffers. This can be used in conjunction with the @ref paComplete stream callback return value (see below) to avoid blocking on a call to Pa_StopStream() while queued audio data is still playing.
+
+@subsection callback_io_method The Callback I/O Method
+
+So-called 'callback Streams' operate by periodically invoking a callback function you supply to Pa_OpenStream(). The callback function must implement the @ref PaStreamCallback signature. It gets called by PortAudio every time PortAudio needs your application to consume or produce audio data. The callback is passed pointers to buffers containing the audio to process. The format (interleave, sample data type) and size of these buffers is determined by the parameters passed to Pa_OpenStream() when the Stream was opened.
+
+Stream callbacks usually return @ref paContinue to indicate that PortAudio should keep the stream running. It is possible to deactivate a Stream from the stream callback by returning either @ref paComplete or @ref paAbort. In this case the Stream enters a deactivated state after the last buffer has finished playing (@ref paComplete) or as soon as possible (@ref paAbort). You can detect the deactivated state by calling Pa_IsStreamActive() or by using Pa_SetStreamFinishedCallback() to subscribe to a stream finished notification. Note that even if the stream callback returns @ref paComplete it's still necessary to call Pa_StopStream() or Pa_AbortStream() to enter the stopped state.
+
+Many of the tests in the /tests directory of the PortAudio distribution implement PortAudio stream callbacks. For example see: patest_sine.c (audio output), patest_record.c (audio input), patest_wire.c (audio pass-through) and pa_fuzz.c (simple audio effects processing).
+
+<strong>IMPORTANT:</strong> The stream callback function often needs to operate with very high or real-time priority. As a result there are strict requirements placed on the type of code that can be executed in a stream callback. In general this means avoiding any code that might block, including: acquiring locks, calling OS API functions including allocating memory. With the exception of Pa_GetStreamCpuLoad() you may not call PortAudio API functions from within the stream callback.
+
+@subsection read_write_io_method The Read/Write I/O Method
+
+As an alternative to the callback I/O method, PortAudio provides a synchronous read/write interface for acquiring and playing audio. This can be useful for applications that don't require the lowest possibly latency, or don't warrant the increased complexity of synchronising with an asynchronous callback function. This I/O method is also useful when calling PortAudio from programming languages that don't support asynchronous callbacks. 
+
+To open a Stream in read/write mode you pass a NULL stream callback function pointer to Pa_OpenStream().
+
+To write audio data to a Stream call Pa_WriteStream() and to read data call Pa_ReadStream(). These functions will block if the internal buffers are full, making them safe to call in a tight loop. If you want to avoid blocking you can query the amount of available read or write space using Pa_GetStreamReadAvailable() or Pa_GetStreamWriteAvailable() and use the returned values to limit the amount of data you read or write.
+
+For examples of the read/write I/O method see the following examples in the /tests directory of the PortAudio distribution: patest_read_record.c (audio input), patest_write_sine.c (audio output), patest_read_write_wire.c (audio pass-through).
+
+@subsection stream_info Retrieving Stream Information
+
+You can retrieve information about an open Stream by calling Pa_GetStreamInfo(). This returns a @ref PaStreamInfo structure containing the actual input and output latency and sample rate of the stream. It's possible for these values to be different from the suggested values passed to Pa_OpenStream().
+
+When using a callback stream you can call Pa_GetStreamCpuLoad() to retrieve a rough estimate of the amount of CPU time your callback function is using.
+
+@subsection stream_timing Stream Timing Information
+
+When using the callback I/O method your stream callback function receives timing information via a pointer to a PaStreamCallbackTimeInfo structure. This structure contains the current time along with the estimated hardware capture and playback time of the first sample of the input and output buffers. All times are measured in seconds relative to a Stream-specific clock. The current Stream clock time can be retrieved using Pa_GetStreamTime().
+
+You can use the stream callback @ref PaStreamCallbackTimeInfo times in conjunction with timestamps returned by Pa_GetStreamTime() to implement time synchronization schemes such as time aligning your GUI display with rendered audio, or maintaining synchronization between MIDI and audio playback.
+
+@section error_handling Error Handling
+
+Most PortAudio functions return error codes using values from the @ref PaError enumeration. All error codes are negative values. Some functions return values greater than or equal to zero for normal results and a negative error code in case of error.
+
+You can convert @ref PaError error codes to human readable text by calling Pa_GetErrorText().
+
+PortAudio usually tries to translate error conditions into portable @ref PaError error codes. However if an unexpected error is encountered the @ref paUnanticipatedHostError code may be returned. In this case a further mechanism is provided to query for Host API-specific error information. If PortAudio returns @ref paUnanticipatedHostError you can call Pa_GetLastHostErrorInfo() to retrieve a pointer to a @ref PaHostErrorInfo structure that provides more information, including the Host API that encountered the error, a native API error code and error text. 
+
+@section host_api_extensions Host API and Platform-specific Extensions
+
+The public PortAudio API only exposes functionality that can be provided across all target platforms. In some cases individual native audio APIs offer unique functionality. Some PortAudio Host APIs expose this functionality via Host API-specific extensions. Examples include access to low-level buffering and priority parameters, opening a Stream with only a subset of a Device's channels, or accessing channel metadata such as channel names.
+
+Host API-specific extensions are provided in the form of additional functions and data structures defined in Host API-specific header files found in the /include directory.
+
+The @ref PaStreamParameters structure passed to Pa_IsFormatSupported() and Pa_OpenStream() has a field named @ref PaStreamParameters::hostApiSpecificStreamInfo that is sometimes used to pass low level information when opening a Stream.
+
+See the documentation for the individual Host API-specific header files for details of the extended functionality they expose:

+@section overview Overview
+
+PortAudio is a cross-platform, open-source C language library for real-time audio input and output.
+The library provides functions that allow your software to acquire and output real-time audio streams from your computer's hardware audio interfaces. It is designed to simplify writing cross-platform audio applications, and also to simplify the development of audio software in general by hiding the complexities of dealing directly with each native audio API. PortAudio is used to implement sound recording, editing and mixing applications, software synthesizers, effects processors, music players, internet telephony applications, software defined radios and more. Supported platforms include MS Windows, Mac OS X and Linux. Third-party language bindings make it possible to call PortAudio from other programming languages including @ref java_binding "Java", C++, C#, Python, PureBasic, FreePascal and Lazarus.

+/** @page blocking_read_write Blocking Read/Write Functions
+@ingroup tutorial
+
+PortAudio V19 adds a huge advance over previous versions with a feature called Blocking I/O. Although it may have lower performance that the callback method described earlier in this tutorial, blocking I/O is easier to understand and is, in some cases, more compatible with third party systems than the callback method. Most people starting audio programming also find Blocking I/O easier to learn.
+
+Blocking I/O works in much the same way as the callback method except that instead of providing a function to provide (or consume) audio data, you must feed data to (or consume data from) PortAudio at regular intervals, usually inside a loop. The example below, excepted from patest_read_write_wire.c, shows how to open the default device, and pass data from its input to its output for a set period of time. Note that we use the default high latency values to help avoid underruns since we are usually reading and writing audio data from a relatively low priority thread, and there is usually extra buffering required to make blocking I/O work.
+
+Note that not all API's implement Blocking I/O at this point, so for maximum portability or performance, you'll still want to use callbacks.

+/** @page compile_cmake PortAudio on Windows, OS X or Linux via. CMake
+@ingroup tutorial
+
+@section cmake_building Building PortAudio stand-alone on Windows, OS X or Linux
+
+CMake can be used to generate Visual Studio solutions on Windows, Makefiles (on Linux and OS X) and build metadata for other build systems for PortAudio. You should obtain a recent version of CMake from [http://www.cmake.org] if you do not have one already. If you are unfamiliar with CMake, this section will provide some information on using CMake to build PortAudio.
+
+On Linux, CMake serves a very similar purpose to an autotools "configure" script - except it can generate build metadata apart from Makefiles. The equivalent of the following on POSIX'y systems:
+
+    build_path> {portaudio path}/configure --prefix=/install_location
+    build_path> make
+    build_path> make install
+
+Would be:
+
+    build_path> cmake {portaudio path} -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/install_location
+    build_path> make
+    build_path> make install
+
+The "-G" option specifies the type of build metadata which will be generated. You can obtain a list of supported build metadata formats by invoking (on any platform):
+
+    cmake -G
+
+"make install" should install the same set of files that are installed using the usual configure script included with PortAudio along with a few extra files (similar to pkg-config metadata files) which make it easier for other CMake projects to use the installed libraries.
+
+On Windows, you can use CMake to generate Visual Studio project files which can be used to create the PortAudio libraries. The following serves as an example (and should be done from a directory outside the PortAudio tree) which will create Visual Studio 2015 project files targeting a 64-bit build:
+
+    C:\PABUILD> cmake {portaudio path} -G "Visual Studio 14 2015 Win64"
+
+After executing the above, you can either open the generated solution with Visual Studio or use CMake to invoke the build process. The following shows an example of how to build a release configuration (assuming the above command was executed previously in the same directory):
+
+    C:\PABUILD> cmake --build . --config Release
+
+If you want ASIO support you need to obtain the ASIO2 SDK from Steinberg and place it according to \ref compile_windows_asio_msvc. Both ASIO and the DirectX SDK are automatically searched for by the CMake script - if they are found, they will be enabled by default.
+
+@section cmake_using Using PortAudio in your CMake project
+
+PortAudio defines the following CMake targets:
+
+ - "portaudio_static" for a static library and
+ - "portaudio" for a dynamic library
+
+If you installed PortAudio as described above in \ref cmake_building and the install prefix you used (CMAKE_INSTALL_PREFIX) is in your system PATH or CMAKE_MODULE_PATH CMake variable, you should be able to use:
+
+    find_package(portaudio)
+
+To define the "portaudio_static" and "portaudio" targets in your CMake project.
+
+If you do not want to install portaudio into your system but would rather just have it get built as part of your own project (which may be particularly convenient on Windows), you may also use:
+
+    add_subdirectory("path to PortAudio location" "some binary directory" EXCLUDE_FROM_ALL)
+
+EXCLUDE_FROM_ALL is not strictly necessary, but will ensure that targets which you don't use in your project won't get built.

+/** @page compile_linux Building Portaudio for Linux
+@ingroup tutorial
+
+<i>Note: this page has not been reviewed, and may contain errors.</i>
+
+@section comp_linux1 Installing ALSA Development Kit
+
+The OSS sound API is very old and not well supported. It is recommended that you use the ALSA sound API.
+The PortAudio configure script will look for the ALSA SDK. You can install the ALSA SDK on Ubuntu using:
+
+@code
+sudo apt-get install libasound-dev
+@endcode
+
+You might need to use yum, or some other package manager, instead of apt-get on your machine.
+If you do not install ALSA then you might get a message when testing that says you have no audio devices.
+
+You can find out more about ALSA here: http://www.alsa-project.org/
+
+@section comp_linux2 Configuring and Compiling PortAudio
+
+You can build PortAudio in Linux Environments using the standard configure/make tools:
+
+@code
+./configure && make
+@endcode
+
+That will build PortAudio using Jack, ALSA and OSS in whatever combination they are found on your system. For example, if you have Jack and OSS but not ALSA, it will build using Jack and OSS but not ALSA. This step also builds a number of tests, which can be found in the bin directory of PortAudio. It's a good idea to run some of these tests to make sure PortAudio is working correctly.
+
+@section comp_linux3 Using PortAudio in your Projects
+
+To use PortAudio in your apps, you can simply install the .so files:
+
+@code
+sudo make install
+@endcode
+
+Projects built this way will expect PortAudio to be installed on target systems in order to run. If you want to build a more self-contained binary, you may use the libportaudio.a file:
+
+@code
+cp lib/.libs/libportaudio.a /YOUR/PROJECT/DIR
+@endcode
+
+On some systems you may need to use:
+
+@code
+cp /usr/local/lib/libportaudio.a /YOUR/PROJECT/DIR
+@endcode
+
+You may also need to copy portaudio.h, located in the include/ directory of PortAudio into your project. Note that you will usually need to link with the appropriate libraries that you used, such as ALSA and JACK, as well as with librt and libpthread. For example:
+
+@code
+gcc main.c libportaudio.a -lrt -lm -lasound -ljack -pthread -o YOUR_BINARY
+@endcode
+
+@section comp_linux4 Linux Extensions
+
+Note that the ALSA PortAudio back-end adds a few extensions to the standard API that you may take advantage of. To use these functions be sure to include the pa_linux_alsa.h file found in the include file in the PortAudio folder. This file contains further documentation on the following functions:
+
+ PaAlsaStreamInfo/PaAlsa_InitializeStreamInfo::
+  Objects of the !PaAlsaStreamInfo type may be used for the !hostApiSpecificStreamInfo attribute of a !PaStreamParameters object, in order to specify the name of an ALSA device to open directly. Specify the device via !PaAlsaStreamInfo.deviceString, after initializing the object with PaAlsa_InitializeStreamInfo.
+ 
+ PaAlsa_EnableRealtimeScheduling::
+  PA ALSA supports real-time scheduling of the audio callback thread (using the FIFO pthread scheduling policy), via the extension PaAlsa_EnableRealtimeScheduling. Call this on the stream before starting it with the <i>enableScheduling</i> parameter set to true or false, to enable or disable this behaviour respectively.
+ 
+ PaAlsa_GetStreamInputCard::
+  Use this function to get the ALSA-lib card index of the stream's input device.
+ 
+ PaAlsa_GetStreamOutputCard::
+  Use this function to get the ALSA-lib card index of the stream's output device.
+
+Of particular importance is PaAlsa_EnableRealtimeScheduling, which allows ALSA to run at a high priority to prevent ordinary processes on the system from preempting audio playback. Without this, low latency audio playback will be irregular and will contain frequent drop-outs.
+
+@section comp_linux5 Linux Debugging
+
+Eliot Blennerhassett writes:
+
+On linux build, use e.g. "libtool gdb bin/patest_sine8" to debug that program.
+This is because on linux bin/patest_sine8 is a libtool shell script that wraps 
+bin/.libs/patest_sine8  and allows it to find the appropriate libraries within 
+the build tree.

+/** @page compile_mac_coreaudio Building Portaudio for Mac OS X
+@ingroup tutorial
+
+@section comp_mac_ca_1 Requirements
+
+* OS X 10.4 or later. PortAudio v19 currently only compiles and runs on OS X version 10.4 or later. Because of its heavy reliance on memory barriers, it's not clear how easy it would be to back-port PortAudio to OS X version 10.3. Leopard support requires the 2007 snapshot or later.
+
+* Apple's Xcode and its related tools installed in the default location. There is no Xcode project for PortAudio.
+
+* Mac 10.4 SDK. Look for "/Developer/SDKs/MacOSX10.4u.sdk" folder on your system. It may be installed with XCode. If not then you can download it from Apple Developer Connection. http://connect.apple.com/
+
+@section comp_mac_ca_2 Building
+
+To build PortAudio, simply use the Unix-style "./configure && make":
+
+@code
+ ./configure && make
+@endcode
+
+You do <b>not</b> need to do "make install", and we don't recommend it; however, you may be using software that instructs you to do so, in which case you should follow those instructions. (Note from Phil: I had to do "sudo make install" after the command above, otherwise XCode complained that it could not find "/usr/local/lib/libportaudio.dylib" when I compiled an example.)
+
+The result of these steps will be a file named "libportaudio.dylib" in the directory "usr/local/lib/".
+
+By default, this will create universal binaries and therefore requires the Universal SDK from Apple, included with XCode 2.1 and higher. 
+
+@section comp_mac_ca_3 Other Build Options
+
+There are a variety of other options for building PortAudio. The default described above is recommended as it is the most supported and tested; however, your needs may differ and require other options, which are described below.
+
+@subsection comp_mac_ca_3.1 Building Non-Universal Libraries
+
+By default, PortAudio is built as a universal binary. This includes 64-bit versions if you are compiling on 10.5, Leopard. If you want a "thin", or single architecture library, you have two options:
+
+ * build a non-universal library using configure options.
+ * use lipo(1) on whatever part of the library you plan to use.
+
+Note that the first option may require an extremely recent version of PortAudio (February 5th '08 at least).
+
+@subsection comp_mac_ca_3.2 Building with <i>--disable-mac-universal</i>
+
+To build a non-universal library for the host architecture, simply use the <i>--disable-mac-universal</i> option with configure.
+
+@code
+ ./configure --disable-mac-universal && make
+@endcode
+
+The <i>--disable-mac-universal</i> option may also be used in conjunction with environment variables to give you more control over the universal binary build process. For example, to build a universal binary for the i386 and ppc architectures using the 10.4u sdk (which is the default on 10.4, but not 10.5), you might specify this configure command line:
+
+@code
+ CFLAGS="-O2 -g -Wall -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.3" \
+   LDFLAGS="-arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.3" \
+   ./configure --disable-mac-universal --disable-dependency-tracking
+@endcode
+
+For more info, see Apple's documentation on the matter:
+
+ * http://developer.apple.com/technotes/tn2005/tn2137.html
+ * http://developer.apple.com/documentation/Porting/Conceptual/PortingUnix/intro/chapter_1_section_1.html
+
+@subsection comp_mac_ca_3.3 Using lipo
+
+The second option is to build normally, and use lipo (1) to extract the architectures you want. For example, if you want a "thin", i386 library only:
+
+@code
+ lipo lib/.libs/libportaudio.a -thin i386 -output libportaudio.a
+@endcode
+
+or if you want to extract a single architecture fat file:
+
+@code
+ lipo lib/.libs/libportaudio.a -extract i386 -output libportaudio.a
+@endcode
+
+@subsection comp_mac_ca_3.4 Building With Debug Options
+
+By default, PortAudio on the mac is built without any debugging options. This is because asserts are generally inappropriate for a production environment and debugging information has been suspected, though not proven, to cause trouble with some interfaces. If you would like to compile with debugging, you must run configure with the appropriate flags. For example:
+
+@code
+ ./configure --enable-mac-debug && make
+@endcode
+
+This will enable -g and disable -DNDEBUG which will effectively enable asserts.
+
+@section comp_mac_ca_4 Using the Library in XCode Projects
+
+If you are planning to follow the rest of the tutorial, several project types will work. You can create a "Standard Tool" under "Command Line Utility". If you are not following the rest of the tutorial, any type of project should work with PortAudio, but these instructions may not work perfectly.
+
+Once you've compiled PortAudio, the easiest and recommended way to use PortAudio in your XCode project is to add "<portaudio>/include/portaudio.h" and "<portaudio>/lib/.libs/libportaudio.a" to your project. Because "<portaudio>/lib/.libs/" is a hidden directory, you won't be able to navigate to it using the finder or the standard Mac OS file dialogs by clicking on files and folders. You can use command-shift-G in the finder to specify the exact path, or, from the shell, if you are in the portaudio directory, you can enter this command:
+
+@code
+ open lib/.libs
+@endcode
+
+Then drag the "libportaudio.a" file into your XCode project and place it in the "External Frameworks and Libraries" group, if the project type has it. If not you can simply add it to the top level folder of the project.
+
+You will need to add the following frameworks to your XCode project:
+
+ - CoreAudio.framework
+ - AudioToolbox.framework
+ - AudioUnit.framework
+ - CoreServices.framework
+ - CoreFoundation.framework
+
+@section comp_mac_ca_5 Using the Library in Other Projects
+
+For gcc/Make style projects, include "include/portaudio.h" and link "libportaudio.a", and use the frameworks listed in the previous section. How you do so depends on your build.
+
+@section comp_mac_ca_6 Using Mac-only Extensions to PortAudio
+
+For additional, Mac-only extensions to the PortAudio interface, you may also want to grab "include/pa_mac_core.h". This file contains some special, mac-only features relating to sample-rate conversion, channel mapping, performance and device hogging. See "src/hostapi/coreaudio/notes.txt" for more details on these features.
+
+@section comp_mac_ca_7 What Happened to Makefile.darwin?
+
+Note, there used to be a special makefile just for darwin. This is no longer supported because you can build universal binaries from the standard configure routine. If you find this file in your directory structure it means you have an outdated version of PortAudio.
+
+@code
+ make -f Makefile.darwin
+@endcode

+/** @page compile_windows Building PortAudio for Windows using Microsoft Visual Studio
+@ingroup tutorial
+
+Below is a list of steps to build PortAudio into a dll and lib file. The resulting dll file may contain all five current win32 PortAudio APIs: MME, DirectSound, WASAPI, WDM/KS and ASIO, depending on the preprocessor definitions set in step 9 below.
+
+PortAudio can be compiled using Visual C++ Express Edition which is available free from Microsoft. If you do not already have a C++ development environment, simply download and install. These instructions have been observed to succeed using Visual Studio 2010 as well.
+
+1) Building PortAudio with DirectSound support requires the files <i>dsound.h</i> and <i>dsconf.h</i>. Download and install the DirectX SDK from http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=3021d52b-514e-41d3-ad02-438a3ba730ba to obtain these files. If you installed the DirectX SDK then the DirectSound libraries and header files should be found automatically by Visual Studio/Visual C++. If you get an error saying dsound.h or dsconf.h is missing, you will need to add an extra include path to the Visual Studio project file referencing the DirectX includes directory.
+
+2) For ASIO support, download the ASIO SDK from Steinberg at http://www.steinberg.net/en/company/developer.html . The SDK is free, but you will need to set up a developer account with Steinberg. To use the Visual Studio projects mentioned below, copy the entire ASIOSDK2 folder into src\\hostapi\\asio\\. Rename it from ASIOSDK2 to ASIOSDK. To build without ASIO (or other host API) see the "Building without ASIO support" section below.
+
+3) If you have Visual Studio 6.0, 7.0(VC.NET/2001) or 7.1(VC.2003), open portaudio.dsp and convert if needed.
+
+4) If you have Visual Studio 2005, Visual C++ 2008 Express Edition or Visual Studio 2010, open the portaudio.sln file located in build\\msvc\\. Doing so will open Visual Studio or Visual C++. Click "Finish" if a conversion wizard appears. The sln file contains four configurations: Win32 and Win64 in both Release and Debug variants.
+
+@section comp_win1 For Visual Studio 2005, Visual C++ 2008 Express Edition or Visual Studio 2010
+
+The steps below describe settings for recent versions of Visual Studio. Similar settings can be set in earlier versions of Visual Studio.
+
+5) Open Project -> portaudio Properties and select "Configuration Properties" in the tree view.
+
+6) Select "all configurations" in the "Configurations" combo box above. Select "All Platforms" in the "Platforms" combo box.
+
+7) Now set a few options:
+
+Required:
+
+C/C++ -> Code Generation -> Runtime library = /MT
+
+Optional:
+
+C/C++ -> Optimization -> Omit frame pointers = Yes
+
+Optional: C/C++ -> Code Generation -> Floating point model = fast
+
+NOTE: When using PortAudio from C/C++ it is not usually necessary to explicitly set the structure member alignment; the default should work fine. However some languages require, for example, 4-byte alignment. If you are having problems with portaudio.h structure members not being properly read or written to, it may be necessary to explicitly set this value by going to C/C++ -> Code Generation -> Struct member alignment and setting it to an appropriate value (four is a common value). If your compiler is configurable, you should ensure that it is set to use the same structure member alignment value as used for the PortAudio build.
+
+Click "Ok" when you have finished setting these parameters.
+
+@section comp_win2 Preprocessor Definitions
+
+Since the preprocessor definitions are different for each configuration and platform, you'll need to edit these individually for each configuration/platform combination that you want to modify using the "Configurations" and "Platforms" combo boxes.
+
+8) To suppress PortAudio runtime debug console output, go to Project -> Properties -> Configuration Properties -> C/C++ -> Preprocessor. In the field 'Preprocessor Definitions', find PA_ENABLE_DEBUG_OUTPUT and remove it. The console will not output debug messages.
+
+9) Also in the preprocessor definitions you need to explicitly define the native audio APIs you wish to use. For Windows the available API definitions are:
+
+PA_USE_ASIO<br>
+PA_USE_DS (DirectSound)<br>
+PA_USE_WMME (MME)<br>
+PA_USE_WASAPI<br>
+PA_USE_WDMKS<br>
+PA_USE_SKELETON
+
+For each of these, the value of 0 indicates that support for this API should not be included. The value 1 indicates that support for this API should be included. (PA_USE_SKELETON is not usually used, it is a code sample for developers wanting to support a new API).
+
+@section comp_win3 Building
+
+As when setting Preprocessor definitions, building is a per-configuration per-platform process. Follow these instructions for each configuration/platform combination that you're interested in.
+
+10) From the Build menu click Build -> Build solution. For 32-bit compilations, the dll file created by this process (portaudio_x86.dll) can be found in the directory build\\msvc\\Win32\\Release. For 64-bit compilations, the dll file is called portaudio_x64.dll, and is found in the directory build\\msvc\\x64\\Release.
+
+11) Now, any project that requires portaudio can be linked with portaudio_x86.lib (or _x64) and include the relevant headers (portaudio.h, and/or pa_asio.h , pa_x86_plain_converters.h) You may want to add/remove some DLL entry points. At the time of writing the following 6 entries are not part of the official PortAudio API defined in portaudio.h:
+
+(from portaudio.def)
+@code
+...
+PaAsio_GetAvailableLatencyValues    @50
+PaAsio_ShowControlPanel             @51
+PaUtil_InitializeX86PlainConverters @52
+PaAsio_GetInputChannelName          @53
+PaAsio_GetOutputChannelName         @54
+PaUtil_SetLogPrintFunction          @55
+@endcode
+
+@section comp_win4 Building without ASIO support
+
+To build PortAudio without ASIO support you need to:
+
+1) Make sure your project doesn't try to build any ASIO SDK files. If you're using one of the shipped projects, remove the ASIO related files from the project. In the shipped projects you can find them in the project tree under portaudio > Source Files > hostapi > ASIO > ASIOSDK
+
+2) Make sure your project doesn't try to build the PortAudio ASIO implementation files:
+
+@code
+src\\hostapi\\pa_asio.cpp
+src\\hostapi\\iasiothiscallresolver.cpp
+@endcode
+
+If you're using one of the shipped projects, remove them from the project. In the shipped projects you can find them in the project tree under portaudio > Source Files > hostapi > ASIO
+
+3) Define the preprocessor symbols in the project properties as described in step 9 above. In VS2005 this can be accomplished by selecting
+Project Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions. Omitting PA_USE_ASIO or setting it to 0 stops src\\os\\win\\pa_win_hostapis.c from trying to initialize the PortAudio ASIO implementation.
+
+4) Remove PaAsio_* entry points from portaudio.def

+/** @page compile_windows_asio_msvc Building Portaudio for Windows with ASIO support using MSVC
+@ingroup tutorial
+
+@section comp_win_asiomsvc1 Portaudio Windows ASIO with MSVC
+
+This tutorial describes how to build PortAudio with ASIO support using MSVC *from scratch*, without an existing Visual Studio project. For instructions for building PortAudio (including ASIO support) using the bundled Visual Studio project file see the compiling instructions for \ref compile_windows.
+
+ASIO is a low latency audio API from Steinberg. To compile an ASIO
+application, you must first download the ASIO SDK from Steinberg. You also
+need to obtain ASIO drivers for your audio device. Download the ASIO SDK from Steinberg at http://www.steinberg.net/en/company/developer.html . The SDK is free but you will need to set up a developer account with Steinberg.
+
+This tutorial assumes that you have 3 directories set up at the same level (side by side), one containing PortAudio, one containing the ASIO SDK and one containing your Visual Studio project:
+
+@code
+/ASIOSDK2 
+/portaudio
+/DirContainingYourVisualStudioProject  (should directly contain the .sln, .vcproj or .vcprojx etc.)
+@endcode
+
+First, make sure that the Steinberg SDK and the portaudio files are "side by side" in the same directory.
+
+Open Microsoft Visual C++ and create a new blank Console exe Project/Workspace in that same directory.
+
+For example, the paths for all three groups might read like this:
+
+@code
+C:\Program Files\Microsoft Visual Studio\VC98\My Projects\ASIOSDK2
+C:\Program Files\Microsoft Visual Studio\VC98\My Projects\portaudio
+C:\Program Files\Microsoft Visual Studio\VC98\My Projects\Sawtooth
+@endcode
+
+
+Next, add the following Steinberg ASIO SDK files to the project Source Files: 
+
+@code
+asio.cpp                        (ASIOSDK2\common)
+asiodrivers.cpp                 (ASIOSDK2\host)
+asiolist.cpp                    (ASIOSDK2\host\pc)
+@endcode
+
+
+Then, add the following PortAudio files to the project Source Files:
+
+@code
+pa_asio.cpp                     (portaudio\src\hostapi\asio)
+pa_allocation.c                 (portaudio\src\common)
+pa_converters.c                 (portaudio\src\common)
+pa_cpuload.c                    (portaudio\src\common)
+pa_dither.c                     (portaudio\src\common)
+pa_front.c                      (portaudio\src\common)
+pa_process.c                    (portaudio\src\common)
+pa_ringbuffer.c                 (portaudio\src\common)
+pa_stream.c                     (portaudio\src\common)
+pa_trace.c                      (portaudio\src\common)
+pa_win_hostapis.c               (portaudio\src\os\win)
+pa_win_util.c                   (portaudio\src\os\win)
+pa_win_coinitialize.c           (portaudio\src\os\win)
+pa_win_waveformat.c             (portaudio\src\os\win)
+pa_x86_plain_converters.c       (portaudio\src\os\win)
+paex_saw.c                      (portaudio\examples)  (Or another file containing main() 
+                                                      for the console exe to be built.)
+@endcode
+
+
+Although not strictly necessary, you may also want to add the following files to the project Header Files:
+
+@code
+portaudio.h                     (portaudio\include)
+pa_asio.h                       (portaudio\include)
+@endcode
+
+These header files define the interfaces to the PortAudio API.
+
+
+Next, go to Project Settings > All Configurations > C/C++ > Preprocessor > Preprocessor Definitions and add
+PA_USE_ASIO=1 to any entries that might be there.
+
+eg: WIN32;_CONSOLE;_MBCS   changes to    WIN32;_CONSOLE,_MBCS;PA_USE_ASIO=1
+
+Then, on the same Project Settings tab, go down to Additional Include Directories (in VS2010 you'll find this setting under C/C++ > General) and enter the following relative include paths:
+
+@code
+..\portaudio\include;..\portaudio\src\common;..\portaudio\src\os\win;..\asiosdk2\common;..\asiosdk2\host;..\asiosdk2\host\pc
+@endcode
+
+You'll need to make sure the relative paths are correct for the particular directory layout you're using. The above should work fine if you use the side-by-side layout we recommended earlier.
+
+Some source code in the ASIO SDK is not compatible with the Win32 API UNICODE mode (The ASIO SDK expects the non-Unicode Win32 API). Therefore you need to make sure your project is set to not use Unicode. You do this by setting the project Character Set to "Use Multi-Byte Character Set" (NOT "Use Unicode Character Set"). In VS2010 the Character Set option can be found at Configuration Properties > General > Character Set. (An alternative to setting the project to non-Unicode is to patch asiolist.cpp to work when UNICODE is defined: put #undef UNICODE at the top of the file before windows.h is included.)
+
+You should now be able to build any of the test executables in the portaudio\\examples directory.
+We suggest that you start with paex_saw.c because it's one of the simplest example files.

+
+From the [http://www.mingw.org MinGW projectpage]:
+
+MinGW: A collection of freely available and freely distributable
+Windows specific header files and import libraries, augmenting
+the GNU Compiler Collection, (GCC), and its associated
+tools, (GNU binutils). MinGW provides a complete Open Source
+programming tool set which is suitable for the development of
+native Windows programs that do not depend on any 3rd-party C
+runtime DLLs.
+
+MSYS: A Minimal SYStem providing a POSIX compatible Bourne shell
+environment, with a small collection of UNIX command line
+tools. Primarily developed as a means to execute the configure
+scripts and Makefiles used to build Open Source software, but
+also useful as a general purpose command line interface to
+replace Windows cmd.exe.
+
+MinGW provides a compiler/linker toolchain while MSYS is required
+to actually run the PortAudio configure script.
+
+Once MinGW and MSYS are installed (see the [http://www.mingw.org/MinGWiki MinGW-Wiki]) open an MSYS shell and run the famous:
+
+@code
+./configure
+make
+make install
+@endcode
+
+The above should create a working version though you might want to
+provide '--prefix=<path-to-install-dir>' to configure.
+
+'./configure --help' gives details as to what can be tinkered with.

+/** @page open_default_stream Opening a Stream Using Defaults
+@ingroup tutorial
+
+The next step is to open a stream, which is similar to opening a file. You can specify whether you want audio input and/or output, how many channels, the data format, sample rate, etc. Opening a ''default'' stream means opening the default input and output devices, which saves you the trouble of getting a list of devices and choosing one from the list. (We'll see how to do that later.)
+@code
+#define SAMPLE_RATE (44100)
+static paTestData data;
+
+.....
+
+    PaStream *stream;
+    PaError err;
+
+    /* Open an audio I/O stream. */
+    err = Pa_OpenDefaultStream( &stream,
+                                0,          /* no input channels */
+                                2,          /* stereo output */
+                                paFloat32,  /* 32 bit floating point output */
+                                SAMPLE_RATE,
+                                256,        /* frames per buffer, i.e. the number
+                                                   of sample frames that PortAudio will

+                                                   tells PortAudio to pick the best,

+    if( err != paNoError ) goto error;
+@endcode
+
+The data structure and callback are described in \ref writing_a_callback.
+
+The above example opens the stream for writing, which is sufficient for playback. It is also possible to open a stream for reading, to do recording, or both reading and writing, for simultaneous recording and playback or even real-time audio processing. If you plan to do playback and recording at the same time, open only one stream with valid input and output parameters.
+
+There are some caveats to note about simultaneous read/write:
+
+ - Some platforms can only open a read/write stream using the same device.
+ - Although multiple streams can be opened, it is difficult to synchronize them.
+ - Some platforms don't support opening multiple streams on the same device.
+ - Using multiple streams may not be as well tested as other features.
+ - The PortAudio library calls must be made from the same thread or synchronized by the user.

+/** @page querying_devices Enumerating and Querying PortAudio Devices
+@ingroup tutorial
+
+@section tut_query1 Querying Devices
+
+It is often fine to use the default device as we did previously in this tutorial, but there are times when you'll want to explicitly choose the device from a list of available devices on the system. To see a working example of this, check out pa_devs.c in the tests/ directory of the PortAudio source code. To do so, you'll need to first initialize PortAudio and Query for the number of Devices:
+
+@code
+    int numDevices;
+
+    numDevices = Pa_GetDeviceCount();
+    if( numDevices < 0 )
+    {
+        printf( "ERROR: Pa_CountDevices returned 0x%x\n", numDevices );
+        err = numDevices;
+        goto error;
+    }
+@endcode
+
+
+If you want to get information about each device, simply loop through as follows:
+
+@code
+    const   PaDeviceInfo *deviceInfo;
+
+    for( i=0; i<numDevices; i++ )
+    {
+        deviceInfo = Pa_GetDeviceInfo( i );
+        ...
+    }
+@endcode
+
+The Pa_DeviceInfo structure contains a wealth of information such as the name of the devices, the default latency associated with the devices and more. The structure has the following fields:
+
+@code
+int 	structVersion
+const char * 	name
+PaHostApiIndex 	hostApi
+int 	maxInputChannels
+int 	maxOutputChannels
+PaTime 	defaultLowInputLatency
+PaTime 	defaultLowOutputLatency
+PaTime 	defaultHighInputLatency
+PaTime 	defaultHighOutputLatency
+double 	defaultSampleRate
+@endcode
+
+You may notice that you can't determine, from this information alone, whether or not a particular sample rate is supported. This is because some devices support ranges of sample rates, others support, a list of sample rates, and still others support some sample rates and number of channels combinations but not others. To get around this, PortAudio offers a function for testing a particular device with a given format:
+
+@code
+    const PaStreamParameters *inputParameters;
+    const PaStreamParameters *outputParameters;
+    double desiredSampleRate;
+    ...
+    PaError err;
+
+    err = Pa_IsFormatSupported( inputParameters, outputParameters, desiredSampleRate );
+    if( err == paFormatIsSupported )
+    {
+       printf( "Hooray!\n");
+    }
+    else
+    {
+       printf("Too Bad.\n");
+    }
+@endcode
+
+Filling in the inputParameters and outputParameters fields is shown in a moment.
+
+Once you've found a configuration you like, or one you'd like to go ahead and try, you can open the stream by filling in the PaStreamParameters structures, and calling Pa_OpenStream:
+
+@code
+    double srate = ... ;
+    PaStream *stream;
+    unsigned long framesPerBuffer = ... ; //could be paFramesPerBufferUnspecified, in which case PortAudio will do its best to manage it for you, but, on some platforms, the framesPerBuffer will change in each call to the callback
+    PaStreamParameters outputParameters;
+    PaStreamParameters inputParameters;
+
+    bzero( &inputParameters, sizeof( inputParameters ) ); //not necessary if you are filling in all the fields
+    inputParameters.channelCount = inChan;
+    inputParameters.device = inDevNum;
+    inputParameters.hostApiSpecificStreamInfo = NULL;
+    inputParameters.sampleFormat = paFloat32;
+    inputParameters.suggestedLatency = Pa_GetDeviceInfo(inDevNum)->defaultLowInputLatency ;
+    inputParameters.hostApiSpecificStreamInfo = NULL; //See you specific host's API docs for info on using this field
+
+
+    bzero( &outputParameters, sizeof( outputParameters ) ); //not necessary if you are filling in all the fields
+    outputParameters.channelCount = outChan;
+    outputParameters.device = outDevNum;
+    outputParameters.hostApiSpecificStreamInfo = NULL;
+    outputParameters.sampleFormat = paFloat32;
+    outputParameters.suggestedLatency = Pa_GetDeviceInfo(outDevNum)->defaultLowOutputLatency ;
+    outputParameters.hostApiSpecificStreamInfo = NULL; //See you specific host's API docs for info on using this field
+
+    err = Pa_OpenStream(
+                    &stream,
+                    &inputParameters,
+                    &outputParameters,
+                    srate,

+/** @page start_stop_abort Starting, Stopping and Aborting a Stream
+@ingroup tutorial
+
+@section tut_startstop1 Starting, Stopping and Aborting a Stream
+
+PortAudio will not start playing back audio until you start the stream. After calling Pa_StartStream(), PortAudio will start calling your callback function to perform the audio processing.
+
+@code
+    err = Pa_StartStream( stream );
+    if( err != paNoError ) goto error;
+@endcode
+
+You can communicate with your callback routine through the data structure you passed in on the open call, or through global variables, or using other interprocess communication techniques, but please be aware that your callback function may be called at interrupt time when your foreground process is least expecting it. So avoid sharing complex data structures that are easily corrupted like double linked lists, and avoid using locks such as mutexes as this may cause your callback function to block and therefore drop audio. Such techniques may even cause deadlock on some platforms.
+
+PortAudio will continue to call your callback and process audio until you stop the stream. This can be done in one of several ways, but, before we do so, we'll want to see that some of our audio gets processed by sleeping for a few seconds. This is easy to do with Pa_Sleep(), which is used by many of the examples in the patests/ directory for exactly this purpose. Note that, for a variety of reasons, you can not rely on this function for accurate scheduling, so your stream may not run for exactly the same amount of time as you expect, but it's good enough for our example.
+
+@code
+    /* Sleep for several seconds. */
+    Pa_Sleep(NUM_SECONDS*1000);
+@endcode
+
+Now we need to stop playback. There are several ways to do this, the simplest of which is to call Pa_StopStream():
+
+@code
+    err = Pa_StopStream( stream );
+    if( err != paNoError ) goto error;
+@endcode
+
+Pa_StopStream() is designed to make sure that the buffers you've processed in your callback are all played, which may cause some delay. Alternatively, you could call Pa_AbortStream(). On some platforms, aborting the stream is much faster and may cause some data processed by your callback not to be played.
+
+Another way to stop the stream is to return either paComplete, or paAbort from your callback. paComplete ensures that the last buffer is played whereas paAbort stops the stream as soon as possible. If you stop the stream using this technique, you will need to call Pa_StopStream() before starting the stream again.

+/** @page tutorial_start PortAudio Tutorials
+@ingroup tutorial
+
+These tutorials takes you through a hands-on example of using PortAudio to make sound. If you'd prefer to start with a top-down overview of the PortAudio API, check out the @ref api_overview.
+
+@section tut_start1 Downloading
+
+First thing you need to do is download the PortAudio source code either <a href="http://www.portaudio.com/download.html">as a tarball from the website</a>, or <a href="http://www.portaudio.com/usingsvn.html">from the Subversion Repository</a>.
+
+@section tut_start2 Compiling
+
+Once you've downloaded PortAudio you'll need to compile it, which of course, depends on your environment:
+
+ - Windows
+   - \ref compile_windows
+   - \ref compile_windows_mingw
+   - \ref compile_windows_asio_msvc
+ - Mac OS X
+   - \ref compile_mac_coreaudio
+ - POSIX
+   - \ref compile_linux
+
+You can also use CMake to generate project files for PortAudio on Windows, OS X or Linux or include PortAudio easily in your own CMake project. See \ref compile_cmake.
+
+Many platforms with GCC/make can use the simple ./configure && make combination and simply use the resulting libraries in their code.
+
+@section tut_start3 Programming with PortAudio
+
+Below are the steps to writing a PortAudio application using the callback technique:
+
+ - Write a callback function that will be called by PortAudio when audio processing is needed.
+ - Initialize the PA library and open a stream for audio I/O.
+ - Start the stream. Your callback function will be now be called repeatedly by PA in the background.
+ - In your callback you can read audio data from the inputBuffer and/or write data to the outputBuffer.
+ - Stop the stream by returning 1 from your callback, or by calling a stop function.
+ - Close the stream and terminate the library.
+
+In addition to this "Callback" architecture, V19 also supports a "Blocking I/O" model which uses read and write calls which may be more familiar to non-audio programmers. Note that at this time, not all APIs support this functionality.
+
+In this tutorial, we'll show how to use the callback architecture to play a sawtooth wave. Much of the tutorial is taken from the file paex_saw.c, which is part of the PortAudio distribution. When you're done with this tutorial, you'll be armed with the basic knowledge you need to write an audio program. If you need more sample code, look in the "examples" and "test" directory of the PortAudio distribution. Another great source of info is the portaudio.h Doxygen page, which documents the entire V19 API.
+Also see the page for <a href="https://github.com/PortAudio/portaudio/wiki/Tips">tips on programming PortAudio</a>
+on the PortAudio wiki.

+/** @page utility_functions Utility Functions
+@ingroup tutorial
+
+In addition to the functions described elsewhere in this tutorial, PortAudio provides a number of Utility functions that are useful in a variety of circumstances. 
+You'll want to read the portaudio.h reference, which documents the entire V19 API for details, but we'll try to cover the basics here.
+
+@section tut_util2 Version Information
+
+PortAudio offers two functions to determine the PortAudio Version. This is most useful when you are using PortAudio as a dynamic library, but it may also be useful at other times.
+
+@code
+int             Pa_GetVersion (void)
+const char *    Pa_GetVersionText (void)
+@endcode
+
+@section tut_util3 Error Text
+
+PortAudio allows you to get error text from an error number.
+
+@code
+const char *    Pa_GetErrorText (PaError errorCode)
+@endcode
+
+@section tut_util4 Stream State
+
+PortAudio Streams exist in 3 states: Active, Stopped, and Callback Stopped. If a stream is in callback stopped state, you'll need to stop it before you can start it again. If you need to query the state of a PortAudio stream, there are two functions for doing so:
+
+@code
+PaError     Pa_IsStreamStopped (PaStream *stream)
+PaError     Pa_IsStreamActive (PaStream *stream)
+@endcode
+
+@section tut_util5 Stream Info
+
+If you need to retrieve info about a given stream, such as latency, and sample rate info, there's a function for that too:
+
+@code
+const PaStreamInfo *    Pa_GetStreamInfo (PaStream *stream)
+@endcode
+
+@section tut_util6 Stream Time
+
+If you need to synchronise other activities such as display updates or MIDI output with the PortAudio callback you need to know the current time according to the same timebase used by the stream callback timestamps.
+
+@code
+PaTime  Pa_GetStreamTime (PaStream *stream)
+@endcode
+
+@section tut_util6CPU Usage
+
+To determine how much CPU is being used by the callback, use these:
+
+@code
+double  Pa_GetStreamCpuLoad (PaStream *stream)
+@endcode
+
+@section tut_util7 Other utilities
+
+These functions allow you to determine the size of a sample from its format and sleep for a given amount of time. The sleep function should not be used for precise timing or synchronization because it makes few guarantees about the exact length of time it waits. It is most useful for testing.
+
+@code
+PaError Pa_GetSampleSize (PaSampleFormat format)
+void    Pa_Sleep (long msec)
+@endcode

+/** @page writing_a_callback Writing a Callback Function
+@ingroup tutorial
+
+To write a program using PortAudio, you must include the "portaudio.h" include file. You may wish to read "portaudio.h" because it contains a complete description of the PortAudio functions and constants. Alternatively, you could browse the [http://www.portaudio.com/docs/v19-doxydocs/portaudio_8h.html "portaudio.h" Doxygen page]
+@code
+#include "portaudio.h"
+@endcode
+The next task is to write your own "callback" function. The "callback" is a function that is called by the PortAudio engine whenever it has captured audio data, or when it needs more audio data for output.
+
+Before we begin, it's important to realize that the callback is a delicate place. This is because some systems perform the callback in a special thread, or interrupt handler, and it is rarely treated the same as the rest of your code.
+For most modern systems, you won't be able to cause crashes by making disallowed calls in the callback, but if you want your code to produce glitch-free audio, you will have to make sure you avoid function calls that may take an unbounded amount of time
+to execute. Exactly what these are depend on your platform but almost certainly include the following:  memory allocation/deallocation, I/O (including file I/O as well as console I/O, such as printf()), context switching (such as exec() or
+yield()), mutex operations, or anything else that might rely on the OS. If you think short critical sections are safe please go read about priority inversion. Windows and Mac OS schedulers have no real-time safe priority inversion prevention. Other platforms require special mutex flags. In addition, it is not safe to call any PortAudio API functions in the callback except as explicitly permitted in the documentation.
+
+
+Your callback function must return an int and accept the exact parameters specified in this typedef:
+
+@code
+typedef int PaStreamCallback( const void *input,
+                                      void *output,
+                                      unsigned long frameCount,
+                                      const PaStreamCallbackTimeInfo* timeInfo,
+                                      PaStreamCallbackFlags statusFlags,
+                                      void *userData ) ;
+@endcode
+Here is an example callback function from the test file "patests/patest_saw.c". It calculates a simple left and right sawtooth signal and writes it to the output buffer. Notice that in this example, the signals are of float data type. The signals must be between -1.0 and +1.0. You can also use 16 bit integers or other formats which are specified during setup, but floats are easiest to work with. You can pass a pointer to your data structure through PortAudio which will appear as userData.
+
+@code
+typedef struct
+{
+    float left_phase;
+    float right_phase;
+}   
+paTestData;
+
+/* This routine will be called by the PortAudio engine when audio is needed.
+** It may called at interrupt level on some machines so don't do anything
+** that could mess up the system like calling malloc() or free().
+*/ 
+static int patestCallback( const void *inputBuffer, void *outputBuffer,
+                           unsigned long framesPerBuffer,
+                           const PaStreamCallbackTimeInfo* timeInfo,
+                           PaStreamCallbackFlags statusFlags,
+                           void *userData )
+{
+    /* Cast data passed through stream to our structure. */
+    paTestData *data = (paTestData*)userData; 
+    float *out = (float*)outputBuffer;
+    unsigned int i;
+    (void) inputBuffer; /* Prevent unused variable warning. */
+    
+    for( i=0; i<framesPerBuffer; i++ )
+    {
+        *out++ = data->left_phase;  /* left */
+        *out++ = data->right_phase;  /* right */
+        /* Generate simple sawtooth phaser that ranges between -1.0 and 1.0. */
+        data->left_phase += 0.01f;
+        /* When signal reaches top, drop back down. */
+        if( data->left_phase >= 1.0f ) data->left_phase -= 2.0f;
+        /* higher pitch so we can distinguish left and right. */
+        data->right_phase += 0.03f;
+        if( data->right_phase >= 1.0f ) data->right_phase -= 2.0f;
+    }
+    return 0;

+    @brief Generate Pink Noise using Gardner method, and make "waves". Provides an example of how to
+           post stuff to/from the audio callback using lock-free FIFOs implemented by the PA ringbuffer.
+
+    Optimization suggested by James McCartney uses a tree
+    to select which random value to replace.
+<pre>
+    x x x x x x x x x x x x x x x x
+    x   x   x   x   x   x   x   x
+    x       x       x       x
+     x               x
+       x
+</pre>
+    Tree is generated by counting trailing zeros in an increasing index.
+    When the index is zero, no random number is selected.

+/*
+    IMPORTANT:
+
+    WASAPI is implemented for Callback and Blocking interfaces. It supports Shared and Exclusive
+    share modes.
+
+    Exclusive Mode:
+
+        Exclusive mode allows to deliver audio data directly to hardware bypassing
+        software mixing.
+        Exclusive mode is specified by 'paWinWasapiExclusive' flag.
+
+    Callback Interface:
+
+        Provides best audio quality with low latency. Callback interface is implemented in
+        two versions:
+
+        1) Event-Driven:
+        This is the most powerful WASAPI implementation which provides glitch-free
+        audio at around 3ms latency in Exclusive mode. Lowest possible latency for this mode is
+        3 ms for HD Audio class audio chips. For the Shared mode latency can not be
+        lower than 20 ms.
+
+        2) Poll-Driven:
+        Polling is another 2-nd method to operate with WASAPI. It is less efficient than Event-Driven
+        and provides latency at around 10-13ms. Polling must be used to overcome a system bug
+        under Windows Vista x64 when application is WOW64(32-bit) and Event-Driven method simply
+        times out (event handle is never signalled on buffer completion). Please note, such WOW64 bug
+        does not exist in Vista x86 or Windows 7.
+        Polling can be setup by specifying 'paWinWasapiPolling' flag. Our WASAPI implementation detects
+        WOW64 bug and sets 'paWinWasapiPolling' automatically.
+
+    Thread priority:
+
+        Normally thread priority is set automatically and does not require modification. Although
+        if user wants some tweaking thread priority can be modified by setting 'paWinWasapiThreadPriority'
+        flag and specifying 'PaWasapiStreamInfo::threadPriority' with value from PaWasapiThreadPriority
+        enum.
+
+    Blocking Interface:
+
+        Blocking interface is implemented but due to above described Poll-Driven method can not
+        deliver lowest possible latency. Specifying too low latency in Shared mode will result in
+        distorted audio although Exclusive mode adds stability.
+
+    8.24 format:
+
+        If paCustomFormat is specified as sample format then the implementation will understand it
+        as valid 24-bits inside 32-bit container (e.g. wBitsPerSample = 32, Samples.wValidBitsPerSample = 24).
+
+        By using paCustomFormat there will be small optimization when samples are be copied
+        with Copy_24_To_24 by PA processor instead of conversion from packed 3-byte (24-bit) data
+        with Int24_To_Int32.
+
+    Pa_IsFormatSupported:
+
+        To check format with correct Share Mode (Exclusive/Shared) you must supply PaWasapiStreamInfo
+        with flags paWinWasapiExclusive set through member of PaStreamParameters::hostApiSpecificStreamInfo
+        structure.
+
+        If paWinWasapiExplicitSampleFormat flag is provided then implementation will not try to select
+        suitable close format and will return an error instead of paFormatIsSupported. By specifying
+        paWinWasapiExplicitSampleFormat flag it is possible to find out what sample formats are
+        supported by Exclusive or Shared modes.
+
+    Pa_OpenStream:
+
+        To set desired Share Mode (Exclusive/Shared) you must supply
+        PaWasapiStreamInfo with flags paWinWasapiExclusive set through member of
+        PaStreamParameters::hostApiSpecificStreamInfo structure.
+
+    Coding style for parameters and structure members of the public API:
+
+        1) bXXX - boolean, [1 (TRUE), 0 (FALSE)]
+        2) pXXX - pointer
+        3) fnXXX - pointer to function
+        4) structure members are never prefixed with a type distinguisher
+
+
+    UWP/WinRT:
+
+        This platform has number of limitations which do not allow to enumerate audio devices without
+        an additional external help. Enumeration is possible though from C++/CX, check the related API
+        Windows::Devices::Enumeration::DeviceInformation::FindAllAsync().
+
+        The main limitation is an absence of the device enumeration from inside the PA's implementation.
+        This problem can be solved by using the following functions:
+
+        PaWasapiWinrt_SetDefaultDeviceId() - to set default input/output device,
+        PaWasapiWinrt_PopulateDeviceList() - to populate device list with devices.
+
+        Here is an example of populating the device list which can also be updated dynamically depending on
+        whether device was removed from or added to the system:
+
+        ----------------
+
+        std::vector<const UINT16 *> ids, names;
+        std::vector<PaWasapiDeviceRole> role;
+
+        ids.resize(count);
+        names.resize(count);
+        role.resize(count);
+
+        for (UINT32 i = 0; i < count; ++i)
+        {
+            ids[i]   = (const UINT16 *)device_ids[i].c_str();
+            names[i] = (const UINT16 *)device_names[i].c_str();
+            role[i]  = eRoleUnknownFormFactor;
+        }
+
+        PaWasapiWinrt_SetDefaultDeviceId((const UINT16 *)default_device_id.c_str(), !capture);
+        PaWasapiWinrt_PopulateDeviceList(ids.data(), names.data(), role.data(), count, !capture);
+        PaWasapi_UpdateDeviceList();
+
+        ----------------

+ Functions of type PaStreamCallback are implemented by PortAudio clients.

+
+ When a stream is running, PortAudio calls the stream callback periodically.
+ The callback function is responsible for processing buffers of audio samples
+ passed via the input and output parameters.
+
+ The PortAudio stream callback runs at very high or real-time priority.
+ It is required to consistently meet its time deadlines. Do not allocate
+ memory, access the file system, call library functions or call other functions
+ from the stream callback that may block or take an unpredictable amount of
+ time to complete.
+
+ In order for a stream to maintain glitch-free operation the callback
+ must consume and return audio data faster than it is recorded and/or
+ played. PortAudio anticipates that each callback invocation may execute for
+ a duration approaching the duration of frameCount audio frames at the stream
+ sample rate. It is reasonable to expect to be able to utilise 70% or more of
+ the available CPU time in the PortAudio callback. However, due to buffer size
+ adaption and other factors, not all host APIs are able to guarantee audio
+ stability under heavy CPU load with arbitrary fixed callback buffer sizes.
+ When high callback CPU utilisation is required the most robust behavior
+ can be achieved by using paFramesPerBufferUnspecified as the
+ Pa_OpenStream() framesPerBuffer parameter.
+
+ @param input and @param output are either arrays of interleaved samples or;

+ format flag, an array of buffer pointers, one non-interleaved buffer for
+ each channel.

+ The format, packing and number of channels used by the buffers are
+ determined by parameters to Pa_OpenStream().
+
+ @param frameCount The number of sample frames to be processed by
+ the stream callback.
+

+ in the input buffer, the DAC output time of the first sample in the output buffer

+ @param statusFlags Flags indicating whether input and/or output buffers

+ The stream callback should return one of the values in the
+ ::PaStreamCallbackResult enumeration. To ensure that the callback continues

+ returned the callback will not be called again. If paAbort is returned the
+ stream will finish as soon as possible. If paComplete is returned, the stream
+ will continue until all buffers generated by the callback have been played.
+ This may be useful in applications such as soundfile players where a specific
+ duration of output is required. However, it is not necessary to utilize this
+ mechanism as Pa_StopStream(), Pa_AbortStream() or Pa_CloseStream() can also
+ be used to stop the stream. The callback must always fill the entire output

+
+Link object files or libraries together to form another library, or to
+create an executable program.
+
+LINK-COMMAND is a command using the C compiler that you would use to create
+a program from several object files.
+
+The following components of LINK-COMMAND are treated specially:
+
+  -all-static       do not do any dynamic linking at all
+  -avoid-version    do not add a version suffix if possible
+  -bindir BINDIR    specify path to binaries directory (for systems where
+                    libraries must be found in the PATH setting at runtime)
+  -dlopen FILE      \`-dlpreopen' FILE if it cannot be dlopened at runtime
+  -dlpreopen FILE   link in FILE and add its symbols to lt_preloaded_symbols
+  -export-dynamic   allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
+  -export-symbols SYMFILE
+                    try to export only the symbols listed in SYMFILE
+  -export-symbols-regex REGEX
+                    try to export only the symbols matching REGEX
+  -LLIBDIR          search LIBDIR for required installed libraries
+  -lNAME            OUTPUT-FILE requires the installed library libNAME
+  -module           build a library that can dlopened
+  -no-fast-install  disable the fast-install mode
+  -no-install       link a not-installable executable
+  -no-undefined     declare that a library does not refer to external symbols
+  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
+  -objectlist FILE  Use a list of object files found in FILE to specify objects
+  -precious-files-regex REGEX
+                    don't remove output files matching REGEX
+  -release RELEASE  specify package release information
+  -rpath LIBDIR     the created library will eventually be installed in LIBDIR
+  -R[ ]LIBDIR       add LIBDIR to the runtime path of programs and libraries
+  -shared           only do dynamic linking of libtool libraries
+  -shrext SUFFIX    override the standard shared library file extension
+  -static           do not do any dynamic linking of uninstalled libtool libraries
+  -static-libtool-libs
+                    do not do any dynamic linking of libtool libraries
+  -version-info CURRENT[:REVISION[:AGE]]
+                    specify library version info [each variable defaults to 0]
+  -weak LIBNAME     declare that the target provides the LIBNAME interface
+  -Wc,FLAG
+  -Xcompiler FLAG   pass linker-specific FLAG directly to the compiler
+  -Wl,FLAG
+  -Xlinker FLAG     pass linker-specific FLAG directly to the linker
+  -XCClinker FLAG   pass link-specific FLAG to the compiler driver (CC)
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename.  Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.
+
+If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
+using \`ar' and \`ranlib', or on Windows using \`lib'.
+
+If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file
+is created, otherwise an executable program is created."

+README for PABLIO
+Portable Audio Blocking I/O Library
+Author: Phil Burk
+
+PABLIO is a simplified interface to PortAudio that provides
+read/write style blocking I/O.
+
+PABLIO is DEPRECATED. We recommend that people use the blocking I/O calls
+that are now part of the PortAudio API. These are Pa_ReadStream() and
+Pa_WriteStream().
+

+README for PortAudio Loopback Test
+
+Copyright (c) 1999-2010 Phil Burk and Ross Bencina
+See complete license at end of file.
+
+This folder contains code for a single executable that does a standalone test of PortAudio.
+It does not require a human to listen to the result. Instead it listens to itself using
+a loopback cable connected between the audio output and the audio input. Special pop detectors
+and phase analysers can detect errors in the audio stream.
+
+This test can be run from a script as part of a nightly build and test.
+
+--- How to Build the Loopback Test ---
+
+The loopback test is not normally built by the makefile.
+To build the loopback test, enter:
+
+  ./configure && make loopback
+  
+This will build the "bin/paloopback" executable.
+  
+--- How To Run Test ---
+
+Connect stereo cables from one or more output audio devices to audio input devices. 
+The test will scan all the ports and find the cables.
+
+Adjust the volume levels of the hardware so you get a decent signal that will not clip.
+
+Run the test from the command line with the following options:
+
+  -i# Input device ID. Will scan for loopback if not specified.
+  -o# Output device ID. Will scan for loopback if not specified.
+  -r# Sample Rate in Hz. Will use multiple common rates if not specified.
+  -s# Size of callback buffer in frames, framesPerBuffer.
+  -w  Save bad recordings in a WAV file.
+  -dDir  Path for Directory for WAV files. Default is current directory.
+  -m  Just test the DSP Math code and not the audio devices.
+
+If the -w option is set then any tests that fail will save the recording of the broken
+channel in a WAV file. The files will be numbered and shown in the report.
+
+--- ToDo ---
+
+* Add check for harmonic and enharmonic distortion.
+* Measure min/max peak values.
+* Detect DC bias.
+* Test against matrix of devices/APIs and settings.
+* Detect mono vs stereo loopback.
+* More command line options
+   --quick
+   --latency
+   --duration
+* Automated build and test script with cron job.
+* Test on Windows.

+    @brief Self Testing Quality Assurance app for PortAudio
+    Try to open devices and run through all possible configurations.
+    By default, open only the default devices. Command line options support
+    opening every device, or all input devices, or all output devices.
+    This test does not verify that the configuration works well.
+    It just verifies that it does not crash. It requires a human to
+    listen to the sine wave outputs.
+
+    @author Phil Burk  http://www.softsynth.com
+
+    Pieter adapted to V19 API. Test now relies heavily on
+    Pa_IsFormatSupported(). Uses same 'standard' sample rates
+    as in test pa_devs.c.

+ a list of allocated blocks, and can free all allocations at once. This

+/*Noise shaped dither  (March 2000)
+-------------------
+
+This is a simple implementation of highpass triangular-PDF dither with
+2nd-order noise shaping, for use when truncating floating point audio
+data to fixed point.
+
+The noise shaping lowers the noise floor by 11dB below 5kHz (@ 44100Hz
+sample rate) compared to triangular-PDF dither. The code below assumes
+input data is in the range +1 to -1 and doesn't check for overloads!
+
+To save time when generating dither for multiple channels you can do
+things like this:  r3=(r1 & 0x7F)<<8; instead of calling rand() again.
+
+
+
+  int   r1, r2;                //rectangular-PDF random numbers
+  float s1, s2;                //error feedback buffers
+  float s = 0.5f;              //set to 0.0f for no noise shaping
+  float w = pow(2.0,bits-1);   //word length (usually bits=16)
+  float wi= 1.0f/w;
+  float d = wi / RAND_MAX;     //dither amplitude (2 lsb)
+  float o = wi * 0.5f;         //remove dc offset
+  float in, tmp;
+  int   out;
+
+
+//for each sample...
+
+  r2=r1;                               //can make HP-TRI dither by
+  r1=rand();                           //subtracting previous rand()
+
+  in += s * (s1 + s1 - s2);            //error feedback
+  tmp = in + o + d * (float)(r1 - r2); //dc offset and dither
+
+  out = (int)(w * tmp);                //truncate downwards
+  if(tmp<0.0f) out--;                  //this is faster than floor()
+
+  s2 = s1;
+  s1 = in - wi * (float)out;           //error

+16-to-8-bit first-order dither
+
+Type : First order error feedforward dithering code
+References : Posted by Jon Watte
+
+Notes :
+This is about as simple a dithering algorithm as you can implement, but it's
+likely to sound better than just truncating to N bits.
+
+Note that you might not want to carry forward the full difference for infinity.
+It's probably likely that the worst performance hit comes from the saturation
+conditionals, which can be avoided with appropriate instructions on many DSPs
+and integer SIMD type instructions, or CMOV.
+
+Last, if sound quality is paramount (such as when going from > 16 bits to 16
+bits) you probably want to use a higher-order dither function found elsewhere
+on this site.
+
+
+Code :
+// This code will down-convert and dither a 16-bit signed short
+// mono signal into an 8-bit unsigned char signal, using a first
+// order forward-feeding error term dither.
+
+#define uchar unsigned char
+

+ dependent code.
+
+ If either PA_LITTLE_ENDIAN or PA_BIG_ENDIAN is defined already, then no attempt
+ is made to override that setting. This may be useful if you have a better way
+ of determining the platform's endianness. The autoconf mechanism uses this for

+
+ A PA_VALIDATE_ENDIANNESS macro is provided to compare the compile time
+ and runtime endianness and raise an assertion if they don't match.

+    ValidateOpenStreamParameters() checks that parameters to Pa_OpenStream()
+    conform to the expected values as described below. This function is
+    also designed to be used with the proposed Pa_IsFormatSupported() function.
+
+    There are basically two types of validation that could be performed:
+    Generic conformance validation, and device capability mismatch
+    validation. This function performs only generic conformance validation.
+    Validation that would require knowledge of device capabilities is
+    not performed because of potentially complex relationships between
+    combinations of parameters - for example, even if the sampleRate
+    seems ok, it might not be for a duplex stream - we have no way of
+    checking this in an API-neutral way, so we don't try.
+
+    On success the function returns PaNoError and fills in hostApi,
+    hostApiInputDeviceID, and hostApiOutputDeviceID fields. On failure
+    the function returns an error code indicating the first encountered
+    parameter error.
+
+
+    If ValidateOpenStreamParameters() returns paNoError, the following
+    assertions are guaranteed to be true.
+
+    - at least one of inputParameters & outputParmeters is valid (not NULL)
+
+    - if inputParameters & outputParameters are both valid, that
+        inputParameters->device & outputParameters->device  both use the same host api
+
+    PaDeviceIndex inputParameters->device
+        - is within range (0 to Pa_GetDeviceCount-1) Or:
+        - is paUseHostApiSpecificDeviceSpecification and
+            inputParameters->hostApiSpecificStreamInfo is non-NULL and refers
+            to a valid host api
+
+    int inputParameters->channelCount
+        - if inputParameters->device is not paUseHostApiSpecificDeviceSpecification, channelCount is > 0
+        - upper bound is NOT validated against device capabilities
+
+    PaSampleFormat inputParameters->sampleFormat
+        - is one of the sample formats defined in portaudio.h
+
+    void *inputParameters->hostApiSpecificStreamInfo
+        - if supplied its hostApi field matches the input device's host Api
+
+    PaDeviceIndex outputParmeters->device
+        - is within range (0 to Pa_GetDeviceCount-1)
+
+    int outputParmeters->channelCount
+        - if inputDevice is valid, channelCount is > 0
+        - upper bound is NOT validated against device capabilities
+
+    PaSampleFormat outputParmeters->sampleFormat
+        - is one of the sample formats defined in portaudio.h

+ @brief Buffer Processor prototypes. A Buffer Processor performs buffer length
+ adaption, coordinates sample format conversion, and interleaves/deinterleaves
+ channels.
+
+ <h3>Overview</h3>
+
+ The "Buffer Processor" (PaUtilBufferProcessor) manages conversion of audio
+ data from host buffers to user buffers and back again. Where required, the
+ buffer processor takes care of converting between host and user sample formats,
+ interleaving and deinterleaving multichannel buffers, and adapting between host
+ and user buffers with different lengths. The buffer processor may be used with
+ full and half duplex streams, for both callback streams and blocking read/write
+ streams.
+
+ One of the important capabilities provided by the buffer processor is
+ the ability to adapt between user and host buffer sizes of different lengths
+ with minimum latency. Although this task is relatively easy to perform when
+ the host buffer size is an integer multiple of the user buffer size, the
+ problem is more complicated when this is not the case - especially for
+ full-duplex callback streams. Where necessary the adaption is implemented by
+ internally buffering some input and/or output data. The buffer adation
+ algorithm used by the buffer processor was originally implemented by
+ Stephan Letz for the ASIO version of PortAudio, and is described in his
+ Callback_adaption_.pdf which is included in the distribution.
+
+ The buffer processor performs sample conversion using the functions provided
+ by pa_converters.c.
+
+ The following sections provide an overview of how to use the buffer processor.
+ Interested readers are advised to consult the host API implementations for
+ examples of buffer processor usage.
+
+
+ <h4>Initialization, resetting and termination</h4>
+
+ When a stream is opened, the buffer processor should be initialized using
+ PaUtil_InitializeBufferProcessor. This function initializes internal state
+ and allocates temporary buffers as necessary according to the supplied
+ configuration parameters. Some of the parameters correspond to those requested
+ by the user in their call to Pa_OpenStream(), others reflect the requirements
+ of the host API implementation - they indicate host buffer sizes, formats,
+ and the type of buffering which the Host API uses. The buffer processor should
+ be initialized for callback streams and blocking read/write streams.
+
+ Call PaUtil_ResetBufferProcessor to clear any sample data which is present
+ in the buffer processor before starting to use it (for example when
+ Pa_StartStream is called).
+
+ When the buffer processor is no longer used call
+ PaUtil_TerminateBufferProcessor.
+
+
+ <h4>Using the buffer processor for a callback stream</h4>
+
+ The buffer processor's role in a callback stream is to take host input buffers
+ process them with the stream callback, and fill host output buffers. For a
+ full duplex stream, the buffer processor handles input and output simultaneously
+ due to the requirements of the minimum-latency buffer adation algorithm.
+
+ When a host buffer becomes available, the implementation should call
+ the buffer processor to process the buffer. The buffer processor calls the
+ stream callback to consume and/or produce audio data as necessary. The buffer
+ processor will convert sample formats, interleave/deinterleave channels,
+ and slice or chunk the data to the appropriate buffer lengths according to
+ the requirements of the stream callback and the host API.
+
+ To process a host buffer (or a pair of host buffers for a full-duplex stream)
+ use the following calling sequence:
+
+ -# Call PaUtil_BeginBufferProcessing
+ -# For a stream which takes input:
+    - Call PaUtil_SetInputFrameCount with the number of frames in the host input
+        buffer.
+    - Call one of the following functions one or more times to tell the
+        buffer processor about the host input buffer(s): PaUtil_SetInputChannel,
+        PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel.
+        Which function you call will depend on whether the host buffer(s) are
+        interleaved or not.
+    - If the available host data is split across two buffers (for example a
+        data range at the end of a circular buffer and another range at the
+        beginning of the circular buffer), also call
+        PaUtil_Set2ndInputFrameCount, PaUtil_Set2ndInputChannel,
+        PaUtil_Set2ndInterleavedInputChannels,
+        PaUtil_Set2ndNonInterleavedInputChannel as necessary to tell the buffer
+        processor about the second buffer.
+ -# For a stream which generates output:
+    - Call PaUtil_SetOutputFrameCount with the number of frames in the host
+        output buffer.
+    - Call one of the following functions one or more times to tell the
+        buffer processor about the host output buffer(s): PaUtil_SetOutputChannel,
+        PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel.
+        Which function you call will depend on whether the host buffer(s) are
+        interleaved or not.
+    - If the available host output buffer space is split across two buffers
+        (for example a data range at the end of a circular buffer and another
+        range at the beginning of the circular buffer), call
+        PaUtil_Set2ndOutputFrameCount, PaUtil_Set2ndOutputChannel,
+        PaUtil_Set2ndInterleavedOutputChannels,
+        PaUtil_Set2ndNonInterleavedOutputChannel as necessary to tell the buffer
+        processor about the second buffer.
+ -# Call PaUtil_EndBufferProcessing, this function performs the actual data
+    conversion and processing.
+
+
+ <h4>Using the buffer processor for a blocking read/write stream</h4>
+
+ Blocking read/write streams use the buffer processor to convert and copy user
+ output data to a host buffer, and to convert and copy host input data to
+ the user's buffer. The buffer processor does not perform any buffer adaption.
+ When using the buffer processor in a blocking read/write stream the input and
+ output conversion are performed separately by the PaUtil_CopyInput and
+ PaUtil_CopyOutput functions.
+
+ To copy data from a host input buffer to the buffer(s) which the user supplies
+ to Pa_ReadStream, use the following calling sequence.
+
+ - Repeat the following three steps until the user buffer(s) have been filled
+    with samples from the host input buffers:
+     -# Call PaUtil_SetInputFrameCount with the number of frames in the host
+        input buffer.
+     -# Call one of the following functions one or more times to tell the
+        buffer processor about the host input buffer(s): PaUtil_SetInputChannel,
+        PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel.
+        Which function you call will depend on whether the host buffer(s) are
+        interleaved or not.
+     -# Call PaUtil_CopyInput with the user buffer pointer (or a copy of the
+        array of buffer pointers for a non-interleaved stream) passed to
+        Pa_ReadStream, along with the number of frames in the user buffer(s).
+        Be careful to pass a <i>copy</i> of the user buffer pointers to
+        PaUtil_CopyInput because PaUtil_CopyInput advances the pointers to
+        the start of the next region to copy.
+ - PaUtil_CopyInput will not copy more data than is available in the
+    host buffer(s), so the above steps need to be repeated until the user
+    buffer(s) are full.
+
+
+ To copy data to the host output buffer from the user buffers(s) supplied
+ to Pa_WriteStream use the following calling sequence.
+
+ - Repeat the following three steps until all frames from the user buffer(s)
+    have been copied to the host API:
+     -# Call PaUtil_SetOutputFrameCount with the number of frames in the host
+        output buffer.
+     -# Call one of the following functions one or more times to tell the
+        buffer processor about the host output buffer(s): PaUtil_SetOutputChannel,
+        PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel.
+        Which function you call will depend on whether the host buffer(s) are
+        interleaved or not.
+     -# Call PaUtil_CopyOutput with the user buffer pointer (or a copy of the
+        array of buffer pointers for a non-interleaved stream) passed to
+        Pa_WriteStream, along with the number of frames in the user buffer(s).
+        Be careful to pass a <i>copy</i> of the user buffer pointers to
+        PaUtil_CopyOutput because PaUtil_CopyOutput advances the pointers to
+        the start of the next region to copy.
+ - PaUtil_CopyOutput will not copy more data than fits in the host buffer(s),
+    so the above steps need to be repeated until all user data is copied.

+ @brief Single-reader single-writer lock-free ring buffer
+
+ PaUtilRingBuffer is a ring buffer used to transport samples between
+ different execution contexts (threads, OS callbacks, interrupt handlers)
+ without requiring the use of any locks. This only works when there is
+ a single reader and a single writer (ie. one thread or callback writes
+ to the ring buffer, another thread or callback reads from it).
+
+ The PaUtilRingBuffer structure manages a ring buffer containing N
+ elements, where N must be a power of two. An element may be any size
+ (specified in bytes).
+
+ The memory area used to store the buffer elements must be allocated by
+ the client prior to calling PaUtil_InitializeRingBuffer() and must outlive
+ the use of the ring buffer.
+
+ @note The ring buffer functions are not normally exposed in the PortAudio libraries.
+ If you want to call them then you will need to add pa_ringbuffer.c to your application source code.

+ @brief Host API implementation supporting AudioScience cards
+        via the Linux HPI interface.
+
+ <h3>Overview</h3>
+
+ This is a PortAudio implementation for the AudioScience HPI Audio API
+ on the Linux platform. AudioScience makes a range of audio adapters customised
+ for the broadcasting industry, with support for both Windows and Linux.
+ More information on their products can be found on their website:
+
+     http://www.audioscience.com
+
+ Documentation for the HPI API can be found at:
+
+     http://www.audioscience.com/internet/download/sdk/hpi_usermanual_html/html/index.html
+
+ The Linux HPI driver itself (a kernel module + library) can be downloaded from:
+
+     http://www.audioscience.com/internet/download/linux_drivers.htm
+
+ <h3>Implementation strategy</h3>
+
+ *Note* Ideally, AudioScience cards should be handled by the PortAudio ALSA
+ implementation on Linux, as ALSA is the preferred Linux soundcard API. The existence
+ of this host API implementation might therefore seem a bit flawed. Unfortunately, at
+ the time of the creation of this implementation (June 2006), the PA ALSA implementation
+ could not make use of the existing AudioScience ALSA driver. PA ALSA uses the
+ "memory-mapped" (mmap) ALSA access mode to interact with the ALSA library, while the
+ AudioScience ALSA driver only supports the "read-write" access mode. The appropriate
+ solution to this problem is to add "read-write" support to PortAudio ALSA, thereby
+ extending the range of soundcards it supports (AudioScience cards are not the only
+ ones with this problem). Given the author's limited knowledge of ALSA and the
+ simplicity of the HPI API, the second-best solution was born...
+
+ The following mapping between HPI and PA was followed:
+ HPI subsystem => PortAudio host API
+ HPI adapter => nothing specific
+ HPI stream => PortAudio device
+
+ Each HPI stream is either input or output (not both), and can support
+ different channel counts, sampling rates and sample formats. It is therefore
+ a more natural fit to a PA device. A PA stream can therefore combine two
+ HPI streams (one input and one output) into a "full-duplex" stream. These
+ HPI streams can even be on different physical adapters. The two streams ought to be
+ sample-synchronised when they reside on the same adapter, as most AudioScience adapters
+ derive their ADC and DAC clocks from one master clock. When combining two adapters
+ into one full-duplex stream, however, the use of a word clock connection between the
+ adapters is strongly recommended.
+
+ The HPI interface is inherently blocking, making use of read and write calls to
+ transfer data between user buffers and driver buffers. The callback interface therefore
+ requires a helper thread ("callback engine") which periodically transfers data (one thread
+ per PA stream, in fact). The current implementation explicitly sleeps via Pa_Sleep() until
+ enough samples can be transferred (select() or poll() would be better, but currently seems
+ impossible...). The thread implementation makes use of the Unix thread helper functions
+ and some pthread calls here and there. If a unified PA thread exists, this host API
+ implementation might also compile on Windows, as this is the only real Linux-specific
+ part of the code.
+
+ There is no inherent fixed buffer size in the HPI interface, as in some other host APIs.
+ The PortAudio implementation contains a buffer that is allocated during OpenStream and
+ used to transfer data between the callback and the HPI driver buffer. The size of this
+ buffer is quite flexible and is derived from latency suggestions and matched to the
+ requested callback buffer size as far as possible. It can become quite huge, as the
+ AudioScience cards are typically geared towards higher-latency applications and contain
+ large hardware buffers.
+
+ The HPI interface natively supports most common sample formats and sample rates (some
+ conversion is done on the adapter itself).
+
+ Stream time is measured based on the number of processed frames, which is adjusted by the
+ number of frames currently buffered by the HPI driver.
+
+ There is basic support for detecting overflow and underflow. The HPI interface does not
+ explicitly indicate this, so thresholds on buffer levels are used in combination with
+ stream state. Recovery from overflow and underflow is left to the PA client.
+
+ Blocking streams are also implemented. It makes use of the same polling routines that
+ the callback interface uses, in order to prevent the allocation of variable-sized
+ buffers during reading and writing. The framesPerBuffer parameter is therefore still
+ relevant, and this can be increased in the blocking case to improve efficiency.
+
+ The implementation contains extensive reporting macros (slightly modified PA_ENSURE and
+ PA_UNLESS versions) and a useful stream dump routine to provide debugging feedback.
+
+ Output buffer priming via the user callback (i.e. paPrimeOutputBuffersUsingStreamCallback
+ and friends) is not implemented yet. All output is primed with silence.

+
+This document contains information to help you compile PortAudio with 
+ASIO support. If you find any omissions or errors in this document 
+please notify us on the PortAudio mailing list.
+
+NOTE: The Macintosh sections of this document are provided for historical
+reference. They refer to pre-OS X Macintosh. PortAudio no longer
+supports pre-OS X Macintosh. Steinberg does not support ASIO on Mac OS X.
+
+
+Building PortAudio with ASIO support
+------------------------------------
+
+To build PortAudio with ASIO support you need to compile and link with
+pa_asio.c, and files from the ASIO SDK (see below), along with the common 
+PortAudio files from src/common/ and platform specific files from 
+src/os/win/ (for Win32).
+
+If you are compiling with a non-Microsoft compiler on Windows, also 
+compile and link with iasiothiscallresolver.cpp (see below for 
+an explanation).
+
+For some platforms (MingW, Cygwin/MingW), you may simply
+be able to type:
+
+./configure --with-host_os=mingw --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
+make
+
+and life will be good. Make sure you update the above with the correct local
+path to the ASIO SDK.
+
+
+For Microsoft Visual C++ there is an build tutorial here:
+http://www.portaudio.com/trac/wiki/TutorialDir/Compile/WindowsASIOMSVC
+
+
+
+Obtaining the ASIO SDK
+----------------------
+
+In order to build PortAudio with ASIO support, you need to download 
+the ASIO SDK (version 2.0 or later) from Steinberg. Steinberg makes the ASIO 
+SDK available to anyone free of charge, however they do not permit its 
+source code to be distributed.
+
+NOTE: In some cases the ASIO SDK may require patching, see below 
+for further details.
+
+http://www.steinberg.net/en/company/developer.html
+
+If the above link is broken search Google for:
+"download steinberg ASIO SDK"
+
+
+
+Building the ASIO SDK on Windows
+--------------------------------
+
+To build the ASIO SDK on Windows you need to compile and link with the 
+following files from the ASIO SDK:
+
+asio_sdk\common\asio.cpp
+asio_sdk\host\asiodrivers.cpp
+asio_sdk\host\pc\asiolist.cpp
+
+You may also need to adjust your include paths to support inclusion of 
+header files from the above directories.
+
+The ASIO SDK depends on the following COM API functions: 
+CoInitialize, CoUninitialize, CoCreateInstance, CLSIDFromString
+For compilation with MinGW you will need to link with -lole32, for
+Borland compilers link with Import32.lib.
+
+
+
+Non-Microsoft (MSVC) Compilers on Windows including Borland and GCC
+-------------------------------------------------------------------
+
+Steinberg did not specify a calling convention in the IASIO interface 
+definition. This causes the Microsoft compiler to use the proprietary 
+thiscall convention which is not compatible with other compilers, such 
+as compilers from Borland (BCC and C++Builder) and GNU (gcc). 
+Steinberg's ASIO SDK will compile but crash on initialization if 
+compiled with a non-Microsoft compiler on Windows.
+
+PortAudio solves this problem using the iasiothiscallresolver library 
+which is included in the distribution. When building ASIO support for
+non-Microsoft compilers, be sure to compile and link with
+iasiothiscallresolver.cpp. Note that iasiothiscallresolver includes
+conditional directives which cause it to have no effect if it is
+compiled with a Microsoft compiler, or on the Macintosh.
+
+If you use configure and make (see above), this should be handled
+automatically for you.
+
+For further information about the IASIO thiscall problem see this page:
+http://www.rossbencina.com/code/iasio-thiscall-resolver
+
+
+
+Building the ASIO SDK on (Pre-OS X) Macintosh
+---------------------------------------------
+
+To build the ASIO SDK on Macintosh you need to compile and link with the 
+following files from the ASIO SDK:
+
+host/asiodrivers.cpp 
+host/mac/asioshlib.cpp 
+host/mac/codefragements.cpp
+
+You may also need to adjust your include paths to support inclusion of 
+header files from the above directories.
+
+
+
+(Pre-OS X) Macintosh ASIO SDK Bug Patch
+---------------------------------------
+
+There is a bug in the ASIO SDK that causes the Macintosh version to 
+often fail during initialization. Below is a patch that you can apply.
+
+In codefragments.cpp replace getFrontProcessDirectory function with 
+the following one (GetFrontProcess replaced by GetCurrentProcess).
+
+
+bool CodeFragments::getFrontProcessDirectory(void *specs)
+{
+	FSSpec *fss = (FSSpec *)specs;
+	ProcessInfoRec pif;
+	ProcessSerialNumber psn;
+
+	memset(&psn,0,(long)sizeof(ProcessSerialNumber));
+	//  if(GetFrontProcess(&psn) == noErr)  // wrong !!!
+	if(GetCurrentProcess(&psn) == noErr)  // correct !!!
+	{
+		pif.processName = 0;
+		pif.processAppSpec = fss;
+		pif.processInfoLength = sizeof(ProcessInfoRec);
+		if(GetProcessInformation(&psn, &pif) == noErr)
+				return true;
+	}
+	return false;
+}

+	IASIOThiscallResolver.cpp see the comments in iasiothiscallresolver.h for
+    the top level description - this comment describes the technical details of
+    the implementation.
+
+    The latest version of this file is available from:
+    http://www.audiomulch.com/~rossb/code/calliasio
+

+
+    BACKGROUND
+
+    The IASIO interface declared in the Steinberg ASIO 2 SDK declares
+    functions with no explicit calling convention. This causes MSVC++ to default
+    to using the thiscall convention, which is a proprietary convention not
+    implemented by some non-microsoft compilers - notably borland BCC,
+    C++Builder, and gcc. MSVC++ is the defacto standard compiler used by
+    Steinberg. As a result of this situation, the ASIO sdk will compile with
+    any compiler, however attempting to execute the compiled code will cause a
+    crash due to different default calling conventions on non-Microsoft
+    compilers.
+
+    IASIOThiscallResolver solves the problem by providing an adapter class that
+    delegates to the IASIO interface using the correct calling convention
+    (thiscall). Due to the lack of support for thiscall in the Borland and GCC
+    compilers, the calls have been implemented in assembly language.
+
+    A number of macros are defined for thiscall function calls with different
+    numbers of parameters, with and without return values - it may be possible
+    to modify the format of these macros to make them work with other inline
+    assemblers.
+
+
+    THISCALL DEFINITION
+
+    A number of definitions of the thiscall calling convention are floating
+    around the internet. The following definition has been validated against
+    output from the MSVC++ compiler:
+
+    For non-vararg functions, thiscall works as follows: the object (this)
+    pointer is passed in ECX. All arguments are passed on the stack in
+    right to left order. The return value is placed in EAX. The callee
+    clears the passed arguments from the stack.
+
+
+    FINDING FUNCTION POINTERS FROM AN IASIO POINTER
+
+    The first field of a COM object is a pointer to its vtble. Thus a pointer
+    to an object implementing the IASIO interface also points to a pointer to
+    that object's vtbl. The vtble is a table of function pointers for all of
+    the virtual functions exposed by the implemented interfaces.
+
+    If we consider a variable declared as a pointer to IASO:
+
+    IASIO *theAsioDriver
+
+    theAsioDriver points to:
+
+    object implementing IASIO
+    {
+        IASIOvtbl *vtbl
+        other data
+    }
+
+    in other words, theAsioDriver points to a pointer to an IASIOvtbl
+
+    vtbl points to a table of function pointers:
+
+    IASIOvtbl ( interface IASIO : public IUnknown )
+    {
+    (IUnknown functions)
+    0   virtual HRESULT STDMETHODCALLTYPE (*QueryInterface)(REFIID riid, void **ppv) = 0;
+    4   virtual ULONG STDMETHODCALLTYPE (*AddRef)() = 0;
+    8   virtual ULONG STDMETHODCALLTYPE (*Release)() = 0;      
+
+    (IASIO functions)
+    12	virtual ASIOBool (*init)(void *sysHandle) = 0;
+    16	virtual void (*getDriverName)(char *name) = 0;
+    20	virtual long (*getDriverVersion)() = 0;
+    24	virtual void (*getErrorMessage)(char *string) = 0;
+    28	virtual ASIOError (*start)() = 0;
+    32	virtual ASIOError (*stop)() = 0;
+    36	virtual ASIOError (*getChannels)(long *numInputChannels, long *numOutputChannels) = 0;
+    40	virtual ASIOError (*getLatencies)(long *inputLatency, long *outputLatency) = 0;
+    44	virtual ASIOError (*getBufferSize)(long *minSize, long *maxSize,
+            long *preferredSize, long *granularity) = 0;
+    48	virtual ASIOError (*canSampleRate)(ASIOSampleRate sampleRate) = 0;
+    52	virtual ASIOError (*getSampleRate)(ASIOSampleRate *sampleRate) = 0;
+    56	virtual ASIOError (*setSampleRate)(ASIOSampleRate sampleRate) = 0;
+    60	virtual ASIOError (*getClockSources)(ASIOClockSource *clocks, long *numSources) = 0;
+    64	virtual ASIOError (*setClockSource)(long reference) = 0;
+    68	virtual ASIOError (*getSamplePosition)(ASIOSamples *sPos, ASIOTimeStamp *tStamp) = 0;
+    72	virtual ASIOError (*getChannelInfo)(ASIOChannelInfo *info) = 0;
+    76	virtual ASIOError (*createBuffers)(ASIOBufferInfo *bufferInfos, long numChannels,
+            long bufferSize, ASIOCallbacks *callbacks) = 0;
+    80	virtual ASIOError (*disposeBuffers)() = 0;
+    84	virtual ASIOError (*controlPanel)() = 0;
+    88	virtual ASIOError (*future)(long selector,void *opt) = 0;
+    92	virtual ASIOError (*outputReady)() = 0;
+    };
+
+    The numbers in the left column show the byte offset of each function ptr
+    from the beginning of the vtbl. These numbers are used in the code below
+    to select different functions.
+
+    In order to find the address of a particular function, theAsioDriver
+    must first be dereferenced to find the value of the vtbl pointer:
+
+    mov     eax, theAsioDriver
+    mov     edx, [theAsioDriver]  // edx now points to vtbl[0]
+
+    Then an offset must be added to the vtbl pointer to select a
+    particular function, for example vtbl+44 points to the slot containing
+    a pointer to the getBufferSize function.
+
+    Finally vtbl+x must be dereferenced to obtain the value of the function
+    pointer stored in that address:
+
+    call    [edx+44]    // call the function pointed to by
+                        // the value in the getBufferSize field of the vtbl
+
+
+    SEE ALSO
+
+    Martin Fay's OpenASIO DLL at http://www.martinfay.com solves the same
+    problem by providing a new COM interface which wraps IASIO with an
+    interface that uses portable calling conventions. OpenASIO must be compiled
+    with MSVC, and requires that you ship the OpenASIO DLL with your
+    application.
+
+    
+    ACKNOWLEDGEMENTS
+
+    Ross Bencina: worked out the thiscall details above, wrote the original
+    Borland asm macros, and a patch for asio.cpp (which is no longer needed).
+    Thanks to Martin Fay for introducing me to the issues discussed here,
+    and to Rene G. Ceballos for assisting with asm dumps from MSVC++.
+
+    Antti Silvast: converted the original calliasio to work with gcc and NASM
+    by implementing the asm code in a separate file.
+
+	Fraser Adams: modified the original calliasio containing the Borland inline
+    asm to add inline asm for gcc i.e. Intel syntax for Borland and AT&T syntax
+    for gcc. This seems a neater approach for gcc than to have a separate .asm
+    file and it means that we only need one version of the thiscall patch.
+
+    Fraser Adams: rewrote the original calliasio patch in the form of the
+    IASIOThiscallResolver class in order to avoid modifications to files from
+    the Steinberg SDK, which may have had potential licence issues.
+
+    Andrew Baldwin: contributed fixes for compatibility problems with more
+    recent versions of the gcc assembler.

+// ****************************************************************************
+// File:			IASIOThiscallResolver.h
+// Description:     The IASIOThiscallResolver class implements the IASIO
+//					interface and acts as a proxy to the real IASIO interface by
+//                  calling through its vptr table using the thiscall calling
+//                  convention. To put it another way, we interpose
+//                  IASIOThiscallResolver between ASIO SDK code and the driver.
+//                  This is necessary because most non-Microsoft compilers don't
+//                  implement the thiscall calling convention used by IASIO.
+//
+//					iasiothiscallresolver.cpp contains the background of this
+//					problem plus a technical description of the vptr
+//                  manipulations.
+//
+//					In order to use this mechanism one simply has to add
+//					iasiothiscallresolver.cpp to the list of files to compile
+//                  and #include <iasiothiscallresolver.h>
+//
+//					Note that this #include must come after the other ASIO SDK
+//                  #includes, for example:
+//
+//					#include <windows.h>
+//					#include <asiosys.h>
+//					#include <asio.h>
+//					#include <asiodrivers.h>
+//					#include <iasiothiscallresolver.h>
+//
+//					Actually the important thing is to #include
+//                  <iasiothiscallresolver.h> after <asio.h>. We have
+//                  incorporated a test to enforce this ordering.
+//
+//					The code transparently takes care of the interposition by
+//                  using macro substitution to intercept calls to ASIOInit()
+//                  and ASIOExit(). We save the original ASIO global
+//                  "theAsioDriver" in our "that" variable, and then set
+//                  "theAsioDriver" to equal our IASIOThiscallResolver instance.
+//
+// 					Whilst this method of resolving the thiscall problem requires
+//					the addition of #include <iasiothiscallresolver.h> to client
+//                  code it has the advantage that it does not break the terms
+//                  of the ASIO licence by publishing it. We are NOT modifying
+//                  any Steinberg code here, we are merely implementing the IASIO
+//					interface in the same way that we would need to do if we
+//					wished to provide an open source ASIO driver.
+//
+//					For compilation with MinGW -lole32 needs to be added to the
+//                  linker options. For BORLAND, linking with Import32.lib is
+//                  sufficient.
+//
+//					The dependencies are with: CoInitialize, CoUninitialize,
+//					CoCreateInstance, CLSIDFromString - used by asiolist.cpp
+//					and are required on Windows whether ThiscallResolver is used
+//					or not.
+//
+//					Searching for the above strings in the root library path
+//					of your compiler should enable the correct libraries to be
+//					identified if they aren't immediately obvious.
+//
+//                  Note that the current implementation of IASIOThiscallResolver
+//                  is not COM compliant - it does not correctly implement the
+//                  IUnknown interface. Implementing it is not necessary because
+//                  it is not called by parts of the ASIO SDK which call through
+//                  theAsioDriver ptr. The IUnknown methods are implemented as
+//                  assert(false) to ensure that the code fails if they are
+//                  ever called.
+// Restrictions:	None. Public Domain & Open Source distribute freely
+//					You may use IASIOThiscallResolver commercially as well as
+//                  privately.
+//					You the user assume the responsibility for the use of the
+//					files, binary or text, and there is no guarantee or warranty,
+//					expressed or implied, including but not limited to the
+//					implied warranties of merchantability and fitness for a
+//					particular purpose. You assume all responsibility and agree
+//					to hold no entity, copyright holder or distributors liable
+//					for any loss of data or inaccurate representations of data
+//					as a result of using IASIOThiscallResolver.
+// Version:         1.4 Added separate macro CALL_THISCALL_1_DOUBLE from
+//                  Andrew Baldwin, and volatile for whole gcc asm blocks,
+//                  both for compatibility with newer gcc versions. Cleaned up
+//                  Borland asm to use one less register.
+//                  1.3 Switched to including assert.h for better compatibility.
+//                  Wrapped entire .h and .cpp contents with a check for
+//                  _MSC_VER to provide better compatibility with MS compilers.
+//                  Changed Singleton implementation to use static instance
+//                  instead of freestore allocated instance. Removed ASIOExit
+//                  macro as it is no longer needed.
+//                  1.2 Removed semicolons from ASIOInit and ASIOExit macros to
+//                  allow them to be embedded in expressions (if statements).
+//                  Cleaned up some comments. Removed combase.c dependency (it
+//                  doesn't compile with BCB anyway) by stubbing IUnknown.
+//                  1.1 Incorporated comments from Ross Bencina including things
+//					such as changing name from ThiscallResolver to
+//					IASIOThiscallResolver, tidying up the constructor, fixing
+//					a bug in IASIOThiscallResolver::ASIOExit() and improving
+//					portability through the use of conditional compilation
+//					1.0 Initial working version.

+Notes on status of CoreAudio Implementation of PortAudio
+
+Document Last Updated December 9, 2005
+
+There are currently two implementations of PortAudio for Mac Core Audio.
+
+The original is in pa_mac_core_old.c, and the newer, default implementation
+is in pa_mac_core.c.
+Only pa_mac_core.c is currently developed and supported as it uses apple's
+current core audio technology. To select use the old implementation, replace
+pa_mac_core.c with pa_mac_core_old.c (eg. "cp pa_mac_core_auhal.c
+pa_mac_core.c"), then run configure and make as usual.

+Notes on Newer/Default AUHAL implementation:
+
+by Bjorn Roche
+
+Last Updated December 9, 2005
+
+Principle of Operation:
+
+This implementation uses AUHAL for audio I/O. To some extent, it also
+operates at the "HAL" Layer, though this behavior can be limited by
+platform specific flags (see pa_mac_core.h for details). The default
+settings should be reasonable: they don't change the SR of the device and
+don't cause interruptions if other devices are using the device.
+
+Major Software Elements Used: Apple's HAL AUs provide output SR
+conversion transparently, however, only on output, so this
+implementation uses AudioConverters to convert the sample rate on input.
+A PortAudio ring buffer is used to buffer input when sample rate
+conversion is required or when separate audio units are used for duplex
+IO. Finally, a PortAudio buffer processor is used to convert formats and
+provide additional buffers if needed. Internally, interleaved floating
+point data streams are used exclusively - the audio unit converts from
+the audio hardware's native format to interleaved float PCM and
+PortAudio's Buffer processor is used for conversion to user formats.
+
+Simplex Input: Simplex input uses a single callback. If sample rate
+conversion is required, a ring buffer and AudioConverter are used as
+well.
+
+Simplex output: Simplex output uses a single callback. No ring buffer or
+audio converter is used because AUHAL does its own output SR conversion.
+
+Duplex, one device (no SR conversion): When one device is used, a single
+callback is used. This achieves very low latency.
+
+Duplex, separate devices or SR conversion: When SR conversion is
+required, data must be buffered before it is converted and data is not
+always available at the same times on input and output, so SR conversion
+requires the same treatment as separate devices. The input callback
+reads data and puts it in the ring buffer. The output callback reads the
+data off the ring buffer, into an audio converter and finally to the
+buffer processor.
+
+Platform Specific Options:
+
+By using the flags in pa_mac_core.h, the user may specify several options.
+For example, the user can specify the sample-rate conversion quality, and
+the extent to which PA will attempt to "play nice" and to what extent it
+will interrupt other apps to improve performance. For example, if 44100 Hz
+sample rate is requested but the device is set at 48000 Hz, PA can either
+change the device for optimal playback ("Pro" mode), which may interrupt
+other programs playing back audio, or simple use a sample-rate conversion,
+which allows for friendlier sharing of the device ("Play Nice" mode).
+
+Additionally, the user may define a "channel mapping" by calling
+paSetupMacCoreChannelMap() on their stream info structure before opening
+the stream with it. See below for creating a channel map.
+
+Known issues:
+
+- Buffering: No buffering beyond that provided by core audio is provided
+except where absolutely needed for the implementation to work. This may cause
+issues with large framesPerBuffer settings and it also means that no additional
+latency will be provided even if a large latency setting is selected.
+
+- Latency: Latency settings are generally ignored. They may be used as a
+hint for buffer size in paHostFramesPerBufferUnspecified, or the value may
+be used in cases where additional buffering is needed, such as doing input and
+output on separate devices. Latency settings are always automatically bound
+to "safe" values, however, so setting extreme values here should not be
+an issue.
+
+- Buffer Size: paHostFramesPerBufferUnspecified and specific host buffer sizes
+are supported. paHostFramesPerBufferUnspecified works best in "pro" mode,
+where the buffer size and sample rate of the audio device is most likely
+to match the expected values. In the case of paHostFramesPerBuffer, an
+appropriate framesPerBuffer value will be used that guarantees minimum
+requested latency if that's possible.
+
+- Timing info. It reports on stream time, but I'm probably doing something
+wrong since patest_sine_time often reports negative latency numbers. Also,
+there are currently issues with some devices whehn plugging/unplugging
+devices.
+
+- xrun detection: The only xrun detection performed is when reading
+and writing the ring buffer. There is probably more that can be done.
+
+- abort/stop issues: stopping a stream is always a complete operation,
+but latency should be low enough to make the lack of a separate abort
+unnecessary. Apple clarifies its AudioOutputUnitStop() call here:
+http://lists.apple.com/archives/coreaudio-api/2005/Dec/msg00055.html
+
+- blocking interface: should work fine.
+
+- multichannel: It has been tested successfully on multichannel hardware
+from MOTU: traveler and 896HD. Also Presonus firepod and others. It is
+believed to work with all Core Audio devices, including virtual devices
+such as soundflower.
+
+- sample rate conversion quality: By default, SR conversion is the maximum
+available. This can be tweaked using flags pa_mac_core.h. Note that the AU
+render quyality property is used to set the sample rate conversion quality
+as "documented" here:
+http://lists.apple.com/archives/coreaudio-api/2004/Jan/msg00141.html
+
+- x86/Universal Binary: Universal binaries can be build.
+
+
+
+Creating a channel map:
+
+How to create the map array -  Text taken From AUHAL.rtfd :
+[3] Channel Maps
+Clients can tell the AUHAL units which channels of the device they are interested in.  For example, the client may be processing stereo data, but outputting to a six-channel device.  This is done by using the kAudioOutputUnitProperty_ChannelMap property.  To use this property:
+
+For Output:
+Create an array of SInt32 that is the size of the number of channels of the device (Get the Format of the AUHAL's output Element == 0)
+Initialize each of the array's values to -1 (-1 indicates that that channel is NOT to be presented in the conversion.)
+
+Next, for each channel of your app's output, set:
+channelMapArray[deviceOutputChannel] = desiredAppOutputChannel.
+
+For example: we have a 6 channel output device and our application has a stereo source it wants to provide to the device.  Suppose we want that stereo source to go to the 3rd and 4th channels of the device. The channel map would look like this: { -1, -1, 0, 1, -1, -1 }
+
+Where the formats are:
+Input Element == 0: 2 channels (- client format - settable)
+Output Element == 0: 6 channels (- device format - NOT settable)
+
+So channel 2 (zero-based) of the device will take the first channel of output and channel 3 will take the second channel of output. (This translates to the 3rd and 4th plugs of the 6 output plugs of the device of course!)
+
+For Input:
+Create an array of SInt32 that is the size of the number of channels of the format you require for input.  Get (or Set in this case as needed) the AUHAL's output Element == 1.
+
+Next, for each channel of input you require, set:
+channelMapArray[desiredAppInputChannel] = deviceOutputChannel;
+
+For example: we have a 6 channel input device from which we wish to receive stereo input from the 3rd and 4th channels. The channel map looks like this: { 2, 3 }
+
+Where the formats are:
+Input Element == 0: 2 channels (- device format - NOT settable)
+Output Element == 0: 6 channels (- client format - settable)
+
+

+----------------------------------------
+
+Notes on Original implementation:
+
+by Phil Burk and Darren Gibbs
+
+Last updated March 20, 2002
+
+WHAT WORKS
+
+Output with very low latency, <10 msec.
+Half duplex input or output.
+Full duplex on the same CoreAudio device.
+The paFLoat32, paInt16, paInt8, paUInt8 sample formats.
+Pa_GetCPULoad()
+Pa_StreamTime()
+
+KNOWN BUGS OR LIMITATIONS
+
+We do not yet support simultaneous input and output on different 
+devices. Note that some CoreAudio devices like the Roland UH30 look 
+like one device but are actually two different CoreAudio devices. The 
+Built-In audio is typically one CoreAudio device.
+
+Mono doesn't work.
+
+DEVICE MAPPING
+
+CoreAudio devices can support both input and output. But the sample 
+rates supported may be different. So we have map one or two PortAudio 
+device to each CoreAudio device depending on whether it supports 
+input, output or both.
+
+When we query devices, we first get a list of CoreAudio devices. Then 
+we scan the list and add a PortAudio device for each CoreAudio device 
+that supports input. Then we make a scan for output devices.

+    FindDevicePnpInterfaces fills in the pnpInterface fields in deviceNamesAndGUIDs
+    with UNICODE file paths to the devices. The DS documentation mentions
+    at least two techniques by which these Interface paths can be found using IKsPropertySet on
+    the DirectSound class object. One is using the DSPROPERTY_DIRECTSOUNDDEVICE_DESCRIPTION
+    property, and the other is using DSPROPERTY_DIRECTSOUNDDEVICE_ENUMERATE.
+    I tried both methods and only the second worked. I found two postings on the
+    net from people who had the same problem with the first method, so I think the method used here is
+    more common/likely to work. The problem is that IKsPropertySet_Get returns S_OK
+    but the fields of the device description are not filled in.
+
+    The mechanism we use works by registering an enumeration callback which is called for
+    every DSound device. Our callback searches for a device in our deviceNamesAndGUIDs list
+    with the matching GUID and copies the pointer to the Interface path.
+    Note that we could have used this enumeration callback to perform the original
+    device enumeration, however we choose not to so we can disable this step easily.
+

+-------------------------------------------
+Microsoft Visual Studio 2005 SP1 and higher
+-------------------------------------------
+No specific action is required to compile WASAPI API under Visual Studio.
+You are only required to install min. Windows Vista SDK (v6.0A) prior
+the compilation. To compile with WASAPI specific functionality for Windows 8
+and higher the min. Windows 8 SDK is required.
+
+----------------------------------------
+MinGW (GCC 32/64-bit)
+----------------------------------------
+To compile with MinGW you are required to include 'mingw-include' directory
+which contains necessary files with WASAPI API. These files are modified
+for the compatibility with MinGW compiler. These files are taken from 
+the Windows Vista SDK (v6.0A). MinGW compilation is tested and proved to be
+fully working.
+MinGW   (32-bit) tested min. version: gcc version 4.4.0 (GCC)

+@brief Portaudio WDM-KS host API.
+
+@note This is the implementation of the Portaudio host API using the
+Windows WDM/Kernel Streaming API in order to enable very low latency
+playback and recording on all modern Windows platforms (e.g. 2K, XP, Vista, Win7)
+Note: This API accesses the device drivers below the usual KMIXER
+component which is normally used to enable multi-client mixing and
+format conversion. That means that it will lock out all other users
+of a device for the duration of active stream using those devices

+Notes about WDM-KS host API
+---------------------------
+
+Status history
+--------------
+16th January 2011:
+Added support for WaveRT device API (Vista and later) for even lesser 
+latency support.
+
+10th November 2005:
+Made following changes:
+ * OpenStream: Try all PaSampleFormats internally if the the chosen
+     format is not supported natively.  This fixed several problems
+     with soundcards that did not take kindly to using 24-bit 3-byte formats.
+ * OpenStream: Make the minimum framesPerHostIBuffer (and framesPerHostOBuffer)
+     the default frameSize for the playback/recording pin.
+ * ProcessingThread: Added a switch to only call PaUtil_EndBufferProcessing
+     if the total input frames equals the total output frames
+
+5th September 2004:
+This is the first public version of the code. It should be considered
+an alpha release with zero guarantee not to crash on any particular 
+system. So far it has only been tested in the author's development
+environment, which means a Win2k/SP2 PIII laptop with integrated 
+SoundMAX driver and USB Tascam US-428 compiled with both MinGW
+(GCC 3.3) and MSVC++6 using the MS DirectX 9 SDK.
+It has been most widely tested with the MinGW build, with most of the
+test programs (particularly paqa_devs and paqa_errs) passing.
+There are some notable failures: patest_out_underflow and both of the
+blocking I/O tests (as blocking I/O is not implemented).
+At this point the code needs to be tested with a much wider variety 
+of configurations and feedback provided from testers regarding
+both working and failing cases.
+
+What is the WDM-KS host API?
+----------------------------
+PortAudio for Windows currently has 3 functional host implementations.
+MME uses the oldest Windows audio API which does not offer good
+play/record latency. 
+DirectX improves this, but still imposes a penalty
+of 10s of milliseconds due to the system mixing of streams from
+multiple applications. 
+ASIO offers very good latency, but requires special drivers which are
+not always available for cheaper audio hardware. Also, when ASIO 
+drivers are available, they are not always so robust because they 
+bypass all of the standardised Windows device driver architecture 
+and hit the hardware their own way.
+Alternatively there are a couple of free (but closed source) ASIO 
+implementations which connect to the lower level Windows 
+"Kernel Streaming" API, but again these require special installation 
+by the user, and can be limited in functionality or difficult to use. 
+
+This is where the PortAudio "WDM-KS" host implementation comes in.
+It directly connects PortAudio to the same Kernel Streaming API which
+those ASIO bridges use. This avoids the mixing penalty of DirectX, 
+giving at least as good latency as any ASIO driver, but it has the
+advantage of working with ANY Windows audio hardware which is available
+through the normal MME/DirectX routes without the user requiring 
+any additional device drivers to be installed, and allowing all 
+device selection to be done through the normal PortAudio API.
+
+Note that in general you should only be using this host API if your 
+application has a real requirement for very low latency audio (<20ms), 
+either because you are generating sounds in real-time based upon 
+user input, or you a processing recorded audio in real time.
+
+The only thing to be aware of is that using the KS interface will
+block that device from being used by the rest of system through
+the higher level APIs, or conversely, if the system is using
+a device, the KS API will not be able to use it. MS recommend that
+you should keep the device open only when your application has focus.
+In PortAudio terms, this means having a stream Open on a WDMKS device.
+
+Usage
+-----
+To add the WDMKS backend to your program which is already using 
+PortAudio, you must define PA_USE_WDMKS=1 in your build file,
+and include the pa_win_wdmks\pa_win_wdmks.c into your build.
+The file should compile in both C and C++.
+You will need a DirectX SDK installed on your system for the
+ks.h and ksmedia.h header files.
+You will need to link to the system "setupapi" library.
+Note that if you use MinGW, you will get more warnings from 
+the DX header files when using GCC(C), and still a few warnings
+with G++(CPP).

+    How it works:
+
+    For both callback and blocking read/write streams we open the MME devices
+    in CALLBACK_EVENT mode. In this mode, MME signals an Event object whenever
+    it has finished with a buffer (either filled it for input, or played it
+    for output). Where necessary, we block waiting for Event objects using
+    WaitMultipleObjects().
+
+    When implementing a PA callback stream, we set up a high priority thread
+    which waits on the MME buffer Events and drains/fills the buffers when
+    they are ready.
+
+    When implementing a PA blocking read/write stream, we simply wait on these
+    Events (when necessary) inside the ReadStream() and WriteStream() functions.

+TODO - This should be moved into a doxydoc page.
+
+For more information on the TestPlan please visit:
+
+  http://www.portaudio.com/trac/wiki/TestPlan
+  
+This directory contains various programs to test PortAudio. The files 
+named patest_* are tests.
+
+All following tests are up to date with the V19 API. They should all compile
+(without any warnings on GCC 3.3). Note that this does not necessarily mean that 
+the tests pass, just that they compile.
+
+    x- paqa_devs.c 
+    x- paqa_errs.c   (needs reviewing)
+    x- patest1.c
+    x- patest_buffer.c
+    x- patest_callbackstop.c
+    x- patest_clip.c (last test fails, dither doesn't currently force clip in V19)
+    x- patest_dither.c
+    x- patest_hang.c
+    x- patest_latency.c
+    x- patest_leftright.c
+    x- patest_longsine.c
+    x- patest_many.c
+    x- patest_maxsines.c
+	x- patest_mono.c
+    x- patest_multi_sine.c
+    x- patest_pink.c
+    x- patest_prime.c
+    x- patest_read_record.c
+    x- patest_record.c
+    x- patest_ringmix.c
+    x- patest_saw.c
+    x- patest_sine.c
+    x- patest_sine8.c
+    x- patest_sine_formats.c
+    x- patest_sine_time.c
+    x- patest_start_stop.c
+    x- patest_stop.c
+    x- patest_sync.c
+    x- patest_toomanysines.c
+	x- patest_two_rates.c
+    x- patest_underflow.c
+    x- patest_wire.c
+    x- patest_write_sine.c
+    x- pa_devs.c
+    x- pa_fuzz.c
+    x- pa_minlat.c
+
+Note that Phil Burk deleted the debug_* tests on 2/26/11. They were just hacked
+versions of old V18 tests. If we need to debug then we can just hack a working V19 test.

+/** @file patest_stop.c
+    @ingroup test_src
+    @brief Test different ways of stopping audio.
+
+    Test the three ways of stopping audio:
+        - calling Pa_StopStream(),
+        - calling Pa_AbortStream(),
+        - and returning a 1 from the callback function.
+
+    A long latency is set up so that you can hear the difference.
+    Then a simple 8 note sequence is repeated twice.
+    The program will print what you should hear.

+    @ingroup test_src
+    @brief Test time stamping and synchronization of audio and video.
+
+    A high latency is used so we can hear the difference in time.
+    Random durations are used so we know we are hearing the right beep
+    and not the one before or after.
+
+    Sequence of events:
+        -# Foreground requests a beep.
+        -# Background randomly schedules a beep.
+        -# Foreground waits for the beep to be heard based on PaUtil_GetTime().
+        -# Foreground outputs video (printf) in sync with audio.
+        -# Repeat.
