Valerio,
The above Unix code should work OOTB on Cygwin. Just compile it and run
it. Note that you'll require at least cygwin1.dll to run the application.
If you're asking how to do this *without* Cygwin, then this is off-topic
for this list, and you should ask somewhere else (e.g., on a Win32 list or
forum). Just to give you a hint, the code above may still work OOTB with
MinGW (see <http://mingw.org/> for project and contact information).
