       roar_vs_buffer - Use buffered mode streams


       #include <roaraudio.h>

       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)
       or roar_vs_run(3).


       vss    The VS object to be used.

       buffer The size of the buffer to be used in bytes.

       writering, readring
              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.
