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);
