On cygwin you'd do just what you mention above.
Using the Win32 API, you'd find a mailing list or newsgroup which was
devoted to this sort of thing and ask there. The cygwin mailing list is
not the place for this kind of win32 question. The whole point of cygwin
is that it provides a UNIX-like way of doing things to avoid these kind
of win32 considerations.
