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 con-
     verting 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);
