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;

}
