Remarks
Windows
NT: The ExitWindows function
asks applications if they want to terminate by sending the WM_QUERYENDSESSION
message to the main window of all running applications.
Windows
95: The ExitWindows function
sends the WM_QUERYENDSESSION message to all applications except the one
that called ExitWindows.
An
application agrees to terminate by returning TRUE when it receives this message
(or by allowing the DefWindowProc function to process the message). If any application
returns FALSE when it receives the WM_QUERYENDSESSION message, the shutdown is
canceled.
After Windows
processes the results of the WM_QUERYENDSESSION message, it sends the
WM_ENDSESSION message with the wParam parameter set to TRUE if the
system is shutting down and to FALSE if it is not.
Windows does
not allow new applications to start up during the shutdown process.
