       #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  recom-
	      mended 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);
