SDL_CDOpen - Opens a CD-ROM drive for access.


#include "SDL.h" SDL_CD *SDL_CDOpen(int drive);


Opens a CD-ROM drive for access. It returns a SDL_CD structure on suc- cess, 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.


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);
