- @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.
