DWORD dwReserved,
| // reserved
| UINT uReserved
| // reserved
| );
|
|

Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
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.
