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 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.
