SDL_CDStatus(3) 						 SDL API Reference						   SDL_CDStatus(3)

NAME
       SDL_CDStatus - Returns the current status of the given drive.

SYNOPSIS
       #include "SDL.h"

       CDstatus  SDL_CDStatus(SDL_CD  *cdrom);	/*  Given  a  status,  returns	true  if there's a disk in the drive */ #define CD_INDRIVE(status)
       ((int)status > 0)

DESCRIPTION
       This function returns the current status of the given drive. Status is described like so:

       typedef enum {
	 CD_TRAYEMPTY,
	 CD_STOPPED,
	 CD_PLAYING,
	 CD_PAUSED,
	 CD_ERROR = -1
       } CDstatus;

       If the drive has a CD in it, the table of contents of the CD and current play position of the CD will be stored in the SDL_CD structure.

       The macro CD_INDRIVE is provided for convenience, and given a status returns true if there's a disk in the drive.

	      Note:

	      SDL_CDStatus also updates the SDL_CD structure passed to it.

EXAMPLE
       int playTrack(int track)
       {
	 int playing = 0;

	 if ( CD_INDRIVE(SDL_CDStatus(cdrom)) ) {
	 /* clamp to the actual number of tracks on the CD */
	   if (track >= cdrom->numtracks) {
	     track = cdrom->numtracks-1;
	   }

	   if ( SDL_CDPlayTracks(cdrom, track, 0, 1, 0) == 0 ) {
	     playing = 1;
	   }
	 }
	 return playing;
       }
