SOCKET + recv() is not a general notifier mechanism. WSAPoll is not available on XP, so that's out.
SOCKET does work with select(). As Andrew noted, it's not directly usable in WaitForMultipleObjects(). What do you expect that the caller will need (or want) to do with this thing? -Steve ----- Original Message ----- From: "Darryl L.

So I guess what we're looking at are possibly two different things. I'm looking at EventNotifier to, in the getHandle() method, return something that will work like a file descriptor but on Windows. Is a SOCKET + recv() combination not going to serve that purpose? I'll defer to someone with more Windows experience on this. But to me it seems they should provide the same type of functionality as an FD + polls() or select(). -- Darryl L. Pierce, Sr. Software Engineer @ Red Hat, Inc. Delivering value year after year.
