I think you want to be investigating
WSAEventSelect() and then WaitForMultipleObjectsEx().

WSAEventSelect() claims it needs a WSAEVENT, but according to docs
otherwhere it should accept a standard event handle on NT+ platforms.

WaitForMultiple... will accept pipes, events, anything. (The Ex function
will also allow dispatching of user APCs, see related discussion about
signals)
