Functions
JBU_API void()	ju_buff_init (ju_buff_t *b, size_t s)

JBU_API void()	ju_buff_resize (ju_buff_t *b, size_t s)
	Resizes buffer structure. More...
JBU_API void()	ju_buff_check_size (ju_buff_t *b, size_t s)
	Check size of buffer with requested, and resizes if there is not enough spce. More...
JBU_API void	ju_buff_except (ju_buff_t *b, int(*cb)(ju_buff_t *, ju_ssize_t))
	Underflow/owerflow exception handling. More...
JBU_API size_t()	ju_buff_size (ju_buff_t *b)
	Returns buffer summary size (used and unused). More...
JBU_API size_t()	ju_buff_used (ju_buff_t *b)
	Returns size of buffer busy part. More...
JBU_API size_t()	ju_buff_space (ju_buff_t *b)
	Returns size of buffer empity part. More...
JBU_API size_t()	ju_buff_append (ju_buff_t *b, const void *src, size_t size)
	Adds data from array to te end of the buffer. More...
JBU_API size_t()	ju_buff_fill (ju_buff_t *b, const void *src, size_t size, size_t n)
	Adds data from src array copied N times to the end of the buffer. More...
JBU_API size_t()	ju_buff_remove (ju_buff_t *, void *dst, size_t size)
	Removes data from start of buffer to the dst array. More...
JBU_API void()	ju_buff_move (ju_buff_t *, ju_ssize_t v)
	Moves buffer data forwards or backwards... More...
JBU_API size_t()	ju_buff_read (ju_buff_t *, int fd, size_t)
	Similar to ju_buff_append(), but reads values from the file by descriptor.
JBU_API size_t()	ju_buff_write (ju_buff_t *, int fd, size_t)
	Similar to ju_buff_remove(), but writes values to the the file by descriptor.
JBU_API void *()	ju_buff_data (ju_buff_t *b)
	Returns buffer data from the beginning. More...
JBU_API void()	ju_buff_lock (ju_buff_t *b)
	Locks buffer. More...
JBU_API void()	ju_buff_unlock (ju_buff_t *b)
	Unlocks buffer. More...

Detailed Description

Functions for fixed-size threadsafe FIFO buffer.

This buffer uses char as data type! So use not sample buffers length, but sample buffers sizes.

Sample buffer size == Sample buffer Length * sizeof(ju_sample_t)
