NAME

       roar_vs_role - Update role for a stream

SYNOPSIS

       #include <roaraudio.h>

       int     roar_vs_role          (roar_vs_t * vss, int role, int * error);

DESCRIPTION

       This  function  updates  the  role  of the stream.  This should be done before any read or
       write operation and can be used at any time to update the meta data.

PARAMETERS

       vss    The VS object to be updated.

       role   The new role of the stream.

       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 0.  On error, -1 is returned.

EXAMPLES

        struct roar_keyval kv[2] = {
         {.key = "TITLE",  .value = "Some title"},
         {.key = "ARTIST", .value = "Some artist"}
        };
        ret = roar_vs_meta(vss, &kv, 2, &err);
