First of all we were talking about not documented functionality, not functions.
This clearly can be done with a test application. One of the regression testing
framework primary goal is to test for that kind of things as well.

With undocumented functions I'd primarily rely on the documentation found on
the net, next - inspecting Wine relay traces with a native dll, and only as
a latest resort - look at the disassembly (in the countries where this isn't
