Synopsis
#include "SDL.h"

/* 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_CDStatusalso updates theSDL_CDstructure passed to it.
