According to the WM_ENDESSION docs, when lParam is ENDSESSION_CLOSEAPP and wParam is FALSE, "the application should not shut down".

So, should I just ignore that and use the default response?
What is it's purpose?

(I'm listening to Windows events/messages in Qt (C++) to shutdown some launched processes, but that's just the context and shouldn't have any bearing here...)
