typedef void(* QDBitsProcPtr) (
    BitMap *srcBits, 
    Rect *srcRect, 
    Rect *dstRect, 
    SInt16 mode, 
     maskRgn
);

You would declare your function like this if you were to name it MyQDBitsCallback:

void MyQDBitsCallback (
    BitMap *srcBits, 
    Rect *srcRect, 
    Rect *dstRect, 
    SInt16 mode, 
     maskRgn
);
