I don't have Windows but this example should be parallel and OK. X11 
and SDL documentation don't mention memory addresses. An example of 
clipboard interaction is in https://wiki.libsdl.org/SDL_GetClipboardText .

I infer that the addresses in Clipboard.Mod allow communication with 
Peter's emulator software written in C.  Within that, an SDL  or X11 
library is imported and commands such as SDL_GetClipboardText() are 
invoked.  Plausible?

Thanks,                      ... Lyall E.
