I think the proposed code should give a compiler error (which doesn't mean that it does, of course). Function pointers and data pointers are really different types, and cannot be mixed. They need not even be the same size. If you really want to cast, then cast to the correct type, in this case a function pointer (with matching arguments and return type). However, it is usually better to make sure the prototype of the function is correct, so you don't need the cast. I didn't check if that is possible at all in this case.
