Use Pointer.createConstant() to compare values. BTW, the HWND type is defined in the W32APIS interface.

The copy of JNA I'm working with doesn't have this class yet... I'm using the copy included in JRuby.

In most cases you don't have to "cast" to an int, but if you really, really want to, you can do

new PointerByReference(ptr).getPointer().getInt(0)

It looks like I will have to use this trick, it works well. Pointer doesn't have compareTo, so I can't do the logic I need, where >= 32 is success and < 32 is failure. I guess I could switch to the Ex version of the API as well, but then I would need do define a struct and more things can go wrong...
