Because we are developing some sort of virtual machine and the user can change
the keyboard mapping inside the virtual machine. So I don't need the value,
but the scancode of the key, because I don't know if the user's mapping inside
and outside the virtual machine is equivalent.

Yes, it's for Win32. I got the DLL from here: http://www.gimp.org/win32/ (link
seems broken at the moment). Which DLLs should I use?

Thank you for your long explanation - nevertheless it would be great to get
the hardware_keycode from the keyboard.

I will have a look at it and try it with these functions.
