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.
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);
