NAME

       roar_vs_blocking - Change blocking mode of VS object

SYNOPSIS

       #include <roaraudio.h>

       int     roar_vs_blocking (roar_vs_t * vss, int val, int * error);

DESCRIPTION

       Changes  blocking  mode  of  VS  object  or  ask  for  the  current  mode if val is set to
       ROAR_VS_ASK.

PARAMETERS

       vss    The VS object to be altered.

       val    Specifies the new state. Value must be ROAR_VS_TRUE, ROAR_VS_FALSE,  ROAR_VS_TOGGLE
              or ROAR_VS_ASK.  ROAR_VS_TOGGLE should be avoided.

       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.

RETURN VALUE

       On  success  these  calls  return  the  old  (current if ROAR_VS_ASK is used) state of the
       blocking mode.  On error, -1 is returned.
