That's not C++, but C, but in both "NULL" can be used for both: pointers and ordinals. In Pascal HWND is an ordinal and there the correct equivalent is of course "0". So yes, you should use "0". Maybe you'll need to do this for the first param as well.
As a sidenote: It's always good to inform oneself about the used functions using MSDN. There you'd see what the meaning of "0" or "NULL" in this function is. Here it is btw: http://msdn.microsoft.com/en-us/library/windows/desktop/ms633500%28v=vs.85%29.aspx
