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;
}
