NAME
SDL::CD -- SDL Bindings for structure SDL_CD
CATEGORY
Core, CDROM, Structure
SYNOPSIS
use SDL; use SDL::CDROM; use SDL::CD; SDL::init(SDL_INIT_CDROM); my $drives = SDL::CDROM::num_drives; if( $drives > 0 ) { my $CD = SDL::CD->new( 0 ); if($CD) { ... } }
CONSTANTS
The constants are exported by default. You can avoid this by doing: use SDL::CD (); and access them directly: SDL::CD::CD_TRAYEMPTY; or by choosing the export tags below: Export tag: ':status' CD_TRAYEMPTY CD_STOPPED CD_PLAYING CD_PAUSED CD_ERROR Export tag: ':defaults' CD_FPS SDL_MAX_TRACKS
METHOD
new my $CD = SDL::CD->new($drive) Makes a new SDL::CD object. Returns "undef" if the drive is busy or inaccessible. status my $status = $CD->status(); Returns the current status of the CD tray Returns on of the following constants: • CD_TRAYEMPTY • CD_STOPPED • CD_PLAYING • CD_PAUSED • CD_ERROR play_tracks $CD->play_tracks($start_track, $start_frame, $ntracks, $nframes) Plays the given SDL::CD starting at track $start_track, for $ntracks tracks. $start_frame is the frame offset, from the beginning of the $start_track, at which to start. $nframes is the frame offset, from the beginning of the last track ($start_track+$ntracks), at which to end playing. play_tracks() should only be called after calling "status" to get information about the CD. Note: Data tracks are ignored. Returns 0, or "-1" if there was an error. play $CD->play($start, $length); Plays the given SDL::CD , starting a frame $start for $length frames. Returns 0 on success, "-1" on error pause $CD->pause(); Pauses play on CD Returns 0 on success, or "-1" on an error. resume $CD->resume(); Returns 0 on success, or "-1" on an error. stop $CD->stop(); Stops play on the CD. Returns 0 on success, or "-1" on an error. eject $CD->eject(); Ejects the CD. Returns 0 on success, or "-1" on an error. id $CD->id(); Private drive identifier num_tracks $CD->num_tracks(); Number of tracks on the CD cur_track $CD->cur_track(); Current track on the CD; track my $track = $CD->track($number); Retrieves track description of track $number in CD. See SDL::CDTrack. FRAMES_TO_MSF my ($min, $sec, $fra) = FRAMES_TO_MSF($frames); Conversion functions from frames to Minute/Second/Frames MSF_TO_FRAMES my $frames = MSF_TO_FRAMES($min, $sec, $fra);
