How the function knows about the drawing surface, in which window/surface to paint? Does it implicitly make use of some self pointer? If so, then, what if this function is not called from inside a simple C function then there will not be any self pointer?
Please read the Cocoa Drawing Guide and think about
+[NSGraphicsContext currentContext].
