SDL_CD(3)			SDL API Reference		       SDL_CD(3)

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 second
     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);
