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; - }
