 * compatible with) OGGZ_ERR_STOP_OK in <oggz/oggz_constants.h>.
 * It was badly named, as the preferred functionality distinguishes between
 * a user's OggzReadCallback returning OGGZ_STOP_OK or OGGZ_STOP_ERR; your
 * code should distinguish between these two too :-) Hence, don't use this
 * (unreleased) name in new code.

/**
 * DEPRECATED FUNCTION
 * This function has been replaced with oggz_comments_generate(), which
 * does not require the packet_type argument. Instead, the packet type is
 * determined by the content type of the stream, which was discovered when
 * the bos packet was passed to oggz_write_feed.
 *
 * Output a comment packet for the specified stream.
 * \param oggz A OGGZ* handle (created with OGGZ_WRITE)
 * \param serialno Identify a logical bitstream within \a oggz
 * \param packet_type Type of comment packet to generate,
 * FLAC, OggPCM, Speex, Theora and Vorbis are supported
 * \param FLAC_final_metadata_block Set this to zero unless the packet_type is
 * FLAC, and there are no further metadata blocks to follow. See note below
 * for details.
 * \returns A comment packet for the stream. When no longer needed it
 * should be freed with oggz_packet_destroy().
 * \retval NULL content type does not support comments, not enough memory
 * or comment was too long for FLAC
 * \note FLAC streams may contain multiple metadata blocks of different types.
 * When encapsulated in Ogg the first of these must be a Vorbis comment packet
 * but PADDING, APPLICATION, SEEKTABLE, CUESHEET and PICTURE may follow.
 * The last metadata block must have its first bit set to 1. Since liboggz does
 * not know whether you will supply more metadata blocks you must tell it if
 * this is the last (or only) metadata block by setting
 * FLAC_final_metadata_block to 1.
 * \n As FLAC metadata blocks are limited in size to 16MB minus 1 byte, this
 * function will refuse to produce longer comment packets for FLAC.
 * \n See http://flac.sourceforge.net/format.html for more details.
