Multiple MovieDrawingCompleteUPP's in objective-c

<x-tad-bigger>Hello All

My objective-c application plays multiple movies simultaneously, each movie is owned by an obj-c class instance. I require that each instance of the class receives a MovieDrawingComplete callback and have implemented the code shown below. This works just fine when the first movie is played, but any subsequent movies do not get the callback.

Is it possible to have discreet callbacks for each of my obj-c instances?

Is my use of the SetMovieDrawingCompleteProc refCon wrong?
</x-tad-bigger>

Thanks, Nick


@interface MovieLayer : Layer
{
MovieDrawingCompleteUPP _DrawingCompleteUPP;
Movie _movie;
...
}



@implementation MovieLayer


pascal OSErr _DrawingCompleteProc(Movie theMovie, long refCon)
{
NSLog([(MovieLayer*)refCon name]);

return noErr;
}



- (id)initWithFilename:(NSString *)filename
{
_DrawingCompleteUPP = NewMovieDrawingCompleteUPP(&_DrawingCompleteProc);


...
}


- (void)setLayerPlayEnable:(NSNumber*)flag
{
SetMovieDrawingCompleteProc(_movie, movieDrawingCallWhenChanged, _DrawingCompleteUPP, (self);

...
}
