You shouldn't do that kind of preventive version check, you should
always call the function and then deal with failures appropriately.

Sorry I am a little dense. If both functions are just no-ops on Win9x then the app should not be
calling them anyway right? or if they are then in that mode they would be expecting that return
value?

Thanks

That's why the version checks are unnecessary. Apps that check the
version won't use these functions anyway, and apps that don't check
will just work. There's no point at all in adding extra checks to
deliberately break a function, unless of course an app really depends
on the broken behavior.

OK. Here you go sans superfluous version check.
