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);
