SDL_CDStatus (3) - Linux Manuals

SDL_CDStatus: Returns the current status of the given drive.

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;
}
