Nope. It is just for window messages for the window indicated by the HWND parameter. > Specifically, if I had "handle" returned from RegisterServiceCtrlHandler() > (which as best as I can imagine in my linux centric reality is some sort > alertable mutex like a futex) there are msdn examples showing > WaitForSingleObject() used as an alternative to "global variable polling". I have never used that service control API, no idea what it is used for even... But if MSDN says that the returned SERVICE_STATUS_HANDLE actually is a normal HANDLE and a waitable one even, that can be passed to WaitForSingleObject() and friends, then it should work to use it as the "fd" in a GPollFD. Unfortunately I don't actually know or understand the glib main loop API very well by heart, so I can't say off-hand what you then should do with such a GPollFD. Pass it to g_source_add_poll(), but for what GSource? You might need to implement your own GSource type with relevant callbacks to take care of that handle "firing", and then pass such a GSource object to g_source_attach()?
