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.

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;
}
