Manpages - SDL_CDStatus.3

SDL_CDStatus - Returns the current status of the given drive.

#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)

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.

  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;
  }
