SDL_CDOpen(3) SDL API Reference SDL_CDOpen(3)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);
