lsn_t cdda_disc_firstsector

(

cdrom_drive_t *

d

)

Get first lsn of the first audio track. -1 is returned on error.

References cdda_track_audiop(), cdda_track_firstsector(), cderror(), cdrom_drive_s::opened, and cdrom_drive_s::tracks.

lsn_t cdda_disc_lastsector

(

cdrom_drive_t *

d

)

Get last lsn of the last audio track. The last lssn generally one less than the start of the next track after the audio track. -1 is returned on error.

References cdda_track_audiop(), cdda_track_lastsector(), cderror(), cdrom_drive_s::opened, and cdrom_drive_s::p_cdio.

int cdda_sector_gettrack	(	cdrom_drive_t *	d,
		lsn_t	lsn
	)

Return the track containing the given LSN. If the LSN is before the first track (in the pregap), 0 is returned. If there was an error or the LSN after the LEADOUT (beyond the end of the CD), then CDIO_INVALID_TRACK is returned.

int cdda_track_audiop	(	cdrom_drive_t *	d,
		track_t	i_track
	)

Return 1 is track is an audio track, 0 otherwise.

int cdda_track_channels	(	cdrom_drive_t *	d,
		track_t	i_track
	)

Return the number of channels in track: 2 or 4; -2 if not implemented or -1 for error. Not meaningful if track is not an audio track.

References cdrom_drive_s::p_cdio.

int cdda_track_copyp	(	cdrom_drive_t *	d,
		track_t	i_track
	)

Return 1 is track is an audio track, 0 otherwise.

lsn_t cdda_track_firstsector	(	cdrom_drive_t *	d,
		track_t	i_track
	)

Return the lsn for the start of track i_track or CDIO_LEADOUT_TRACK

lsn_t cdda_track_lastsector	(	cdrom_drive_t *	d,

	)

Get last lsn of the track. The lsn is generally one less than the start of the next track. -1 is returned on error.

int cdda_track_preemp	(	cdrom_drive_t *	d,
		track_t	i_track
	)

Return 1 is audio track has linear preemphasis set, 0 otherwise. Only makes sense for audio tracks.

track_t cdda_tracks

(
