!!NAME


SDL_CDStatus- Returns the current status of the given drive.
!!SYNOPSIS


__#include __


__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
__
!!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
