NAME

       SDL_CDOpen - Opens a CD-ROM drive for access.

SYNOPSIS

       #include "SDL.h"

       SDL_CD *SDL_CDOpen(int drive);

DESCRIPTION

       Opens  a CD-ROM drive for access. It returns a SDL_CD structure on success, or NULL if the drive was invalid or busy. This newly opened CD-
       ROM becomes the default CD used when other CD functions are passed a NULL CD-ROM handle.

       Drives are numbered starting with 0. Drive 0 is the system default CD-ROM.

EXAMPLES

       SDL_CD *cdrom;
       int cur_track;
       int min, sec, frame;
       SDL_Init(SDL_INIT_CDROM);
       atexit(SDL_Quit);

       /* Check for CD drives */
       if(!SDL_CDNumDrives()){
	 /* None found */
	 fprintf(stderr, "No CDROM devices available
       ");
	 exit(-1);
       }

       /* Open the default drive */
       cdrom=SDL_CDOpen(0);

       /* Did if open? Check if cdrom is NULL */
       if(!cdrom){
	 fprintf(stderr, "Couldn't open drive: %s
       ", SDL_GetError());
	 exit(-1);
       }

       /* Print Volume info */
       printf("Name: %s
       ", SDL_CDName(0));
       printf("Tracks: %d
       ", cdrom->numtracks);
       for(cur_track=0;cur_track < cdrom->numtracks; cur_track++){
	 FRAMES_TO_MSF(cdrom->track[cur_track].length, &min, &sec, &frame);
	 printf("     Track %d: Length %d:%d
       ", cur_track, min, sec);
       }

       SDL_CDClose(cdrom);
