Function Documentation

cdda_disc_firstsector()

lsn_t cdda_disc_firstsector

(

cdrom_drive_t *

d

)

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

cdda_disc_lastsector()

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.

cdda_track_firstsector()

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

References cderror(), cdrom_drive_s::disc_toc, TOC_s::dwStartSector, cdrom_drive_s::opened, and cdrom_drive_s::p_cdio.

cdda_track_lastsector()

lsn_t cdda_track_lastsector	(	cdrom_drive_t *	d,
		track_t	i_track )

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

cdda_tracks()

track_t cdda_tracks

(

cdrom_drive_t *

d

)

Return the number of tracks on the or 300 if error.

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

cdio_cddap_sector_gettrack()

int cdio_cddap_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.

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

cdio_cddap_track_audiop()

int cdio_cddap_track_audiop ( cdrom_drive_t * d, track_t i_track )

extern

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

References cdrom_drive_s::p_cdio.

cdio_cddap_track_channels()

int cdio_cddap_track_channels ( cdrom_drive_t * d, track_t i_track )

extern

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.

cdio_cddap_track_copyp()

int cdio_cddap_track_copyp ( cdrom_drive_t * d, track_t i_track )

extern

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

References cdrom_drive_s::p_cdio.

cdio_cddap_track_preemp()

int cdio_cddap_track_preemp ( cdrom_drive_t * d, track_t i_track )

extern

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