roar_vs_buffer - Use buffered mode streams
int roar_vs_buffer(roar_vs_t * vss, size_t buffer, int * error);
ssize_t roar_vs_get_avail_read(roar_vs_t * vss, int * error);
ssize_t roar_vs_get_avail_write(roar_vs_t * vss, int * error);
int roar_vs_reset_buffer(roar_vs_t * vss, int writering, int
readring, int * error);
These functions controls the buffered mode of the VS object. Using this
mode is not recommended.
roar_vs_buffer() initializes the buffered mode. It takes the size for
the buffer as argument. The size should be a power of two. Common
values include 2048 and 4096.
roar_vs_get_avail_read() and roar_vs_get_avail_write() return the
amount of free space in the read and write buffer.
roar_vs_reset_buffer() resets the read and/or write buffer. This means
the data in the buffers is discarded. This does not happen frame
aligned and may result in broken audio.
Buffers are not flushed automaically. To do this use roar_vs_iterate(3)
vss The VS object to be used.
buffer The size of the buffer to be used in bytes.
Selects the buffer to reset. Must be ROAR_VS_TRUE or
error This is a pointer to a integer used to store the error value in
case of error. This can be NULL if not used but it is very
recommended to use this error value to report good error
messages to the user.
On success these calls return 0. roar_vs_get_avail_read() and
roar_vs_get_avail_write() return the free space in the corresponding
buffer. On error, -1 is returned.
