SDL_CDOpen

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\n");
  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\n", SDL_GetError());
  exit(-1);
}

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

SDL_CDClose(cdrom);
