the run-time is aware of the three methods and expects them to be implemented As they are pure virtual, there is no way to create an instance of IUnknown, and so all subclasses must implement all such methods in order to merely compile. There's no danger of not implementing them and only finding that out at runtime (but obviously one can wrongly implement them, of course!). And wow, today I learned Windows #defines a macro with the word interface, presumably because their users can't just (A) see the prefix I in the name or (B) look at the class to see it's an interface. Ugh
