NAME
       SDL_CD - CDROM Drive Information

STRUCTURE DEFINITION
       typedef struct{
	 int id;
	 CDstatus status;
	 int numtracks;
	 int cur_track;
	 int cur_frame;
	 SDL_CDtrack track[SDL_MAX_TRACKS+1];
       } SDL_CD;

STRUCTURE DATA
       id		   Private drive identifier

       status		   Drive status

       numtracks	   Number of tracks on the CD

       cur_track	   Current track

       cur_frame	   Current frame offset within the track

       track[SDL_MAX_TRACKS+1]
			   Array of track descriptions. (see SDL_CDtrack)

DESCRIPTION
       An  SDL_CD structure is returned by SDL_CDOpen. It represents an opened
       CDROM device and stores information on the layout of the tracks on  the
       disc.

       A frame is the base data unit of a CD. CD_FPS frames is equal to 1 sec-
       ond of music. SDL provides two macros for converting between  time  and
       frames: FRAMES_TO_MSF(f, M,S,F) and MSF_TO_FRAMES.

EXAMPLES
       int min, sec, frame;
       int frame_offset;

       FRAMES_TO_MSF(cdrom->cur_frame, &min, &sec, &frame);
       printf("Current Position: %d minutes, %d seconds, %d frames
       ", min, sec, frame);

       frame_offset=MSF_TO_FRAMES(min, sec, frame);
