NAME
roar_vs_meta - Update meta data for a stream
SYNOPSIS
#include <roaraudio.h>
int roar_vs_meta (roar_vs_t * vss, struct roar_keyval * kv, size_t len, int * error);
DESCRIPTION
This function updates meta data 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.
kv An array of meta data elements.
len Length of array kv.
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);
