+## 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

+## 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.

-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 \`..']

-Hello
-
-  This is a small list of steps in order to build portaudio
-(Currently v19-devel) into a VS2005 DLL and lib file.
-This DLL contains all 5 current Win32 PA APIS (MME/DS/ASIO/WASAPI/WDMKS)
-
-1)Copy the source dirs that comes with the ASIO SDK inside src\hostapi\asio\ASIOSDK
-  so you should now have example:
-  
-  portaudio19svn\src\hostapi\asio\ASIOSDK\common
-  portaudio19svn\src\hostapi\asio\ASIOSDK\host
-  portaudio19svn\src\hostapi\asio\ASIOSDK\host\sample
-  portaudio19svn\src\hostapi\asio\ASIOSDK\host\pc
-  portaudio19svn\src\hostapi\asio\ASIOSDK\host\mac (not needed)
-  
-  You dont need "driver"
-
-  To build without ASIO (or another Host API) see the "Building without ASIO support" section below.
-  
-2)
-  *If you have Visual Studio 6.0*, please make sure you have it updated with the latest (and final)
-  microsoft libraries for it, namely:
-  
-  Service pack 5:         
-     Latest known URL:  
-     http://msdn2.microsoft.com/en-us/vstudio/aa718363.aspx 
-	 Yes there EXISTS a service pack 6 , but the processor pack (below) isn't compatible with it.
-	 
-  Processor Pack(only works with above SP5)
-     Latest known URL:
-     http://msdn2.microsoft.com/en-us/vstudio/Aa718349.aspx
-	 This isn't absolutely required for portaudio, but if you plan on using SSE intrinsics and similar things.
-	 Up to you to decide upon Service pack 5 or 6 depending on your need for intrinsics.
-
-  Platform SDK (Feb 2003) : 
-     Latest known URL:  
-     http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm
-	 (This will allow your code base to be x64 friendly, with correct defines 
-	 for LONG_PTR and such)
-	 NOTE A) Yes you have to use IE activex scripts to install that - wont work in Firefox, you 
-	 may have to temporarily change tyour default browser(aint life unfair)
-	 NOTE B) Dont forget to hit "Register PSDK Directories with Visual Studio". 
-	 you can make sure its right in VC6 if you open tools/options/directories/include files and you see SDK 2003 as the FIRST entry
-	 (it must be the same for libs)
-  
-  DirectX 9.0 SDK Update - (Summer 2003)
-    Latest known URL:
-    http://www.microsoft.com/downloads/details.aspx?familyid=9216652f-51e0-402e-b7b5-feb68d00f298&displaylang=en
-    Again register the links in VC6, and check inside vc6 if headers are in second place right after SDk 2003
-	
-  *If you have 7.0(VC.NET/2001) or 7.1(VC.2003) *
-  then I suggest you open portaudio.dsp (and convert if needed)
- 
-  *If you have Visual Studio 2005 * (or later), I suggest you open the portaudio.sln file
-  which contains 2 projects (portaudio & portaudio_static) each with 6 configurations: Win32/x64 in both Debug, Release and ReleaseMinDependency,
-  last of which removes dependency of all but basic OS system DLLs.
-
-  hit compile and hope for the best.
- 
-3)Now in any  project, in which you require portaudio,
-  you can just link with portaudio_x86.lib, (or _x64) and of course include the 
-  relevant headers
-  (portaudio.h, and/or pa_asio.h , pa_x86_plain_converters.h) See (*)
-  
-4) Your new exe should now use portaudio_xXX.dll.
-
-
-Have fun!
-
-(*): you may want to add/remove some DLL entry points.
-Right now those 6 entries are _not_ from portaudio.h
-
-(from portaudio.def)

-*** Building without ASIO support ***
-
-To build PortAudio without ASIO support you need to:
-  A. 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.
-
-  B. Make sure your project doesn't try to build the PortAudio ASIO
-     implementation files:
-	      src/hostapi/pa_asio.cpp
-        src/hostapi/iasiothiscallresolver.cpp
-     If you're using one of the shipped projects remove them from the project.
-
-  C. Set the PA_USE_ASIO preprocessor symbol to zero (i.e. PA_USE_ASIO=0) in the project properties.
-     In VS2005 this can be added under
-     Project Properties > Configuration Properties > C/C++ > Preprocessor > Preprocessor Definitions
-
-     Setting PA_USE_ASIO=0 stops src/os/win/pa_win_hostapis.c 
-     from trying to initialize the PA ASIO implementation.
-
-  D. Remove PaAsio_* entry points from portaudio.def, or comment them out with ;
-
-
-A similar procedure can be used to omit any of the other host APIs from the 
-build. The relevant preprocessor symbols used by pa_win_hostapis.c are:
-PA_USE_WMME, PA_USE_DSOUND, PA_USE_ASIO, PA_USE_WASAPI and PA_USE_WDMKS
