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 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);
