Blocks until the next buffer is returned from the driver. Returns immediately if a buffer is already complete.
The completed buffers are numbered consecutively, so the first call to s16a_wait_for_next_buffer returns the
address of buffer 0, the next will be 1, and so on.

void *s16a_wait_next_buffer(S16aDev *s16a_p);

S16A device handle returned from s16a_open

Address of completed buffer on success; NULL on error. If an error occurs, check the errno global variable
for more information.

 does not fail. This call is not multibuffering, and no transfer is active when

it completes.

int s16a_write(S16aDev *s16a_p, void *buf, int size);

S16A device handle returned from s16a_open

The return value from write; errno is set by write on error.
