Parameters for MyExitWindows()
EWX_LOGOFF
Shuts down
all processes running in the security context of the process that called the
ExitWindowsEx
function. Then it logs the user off.
Alle Prozesse des
Benutzers werden beendet, danach wird der Benutzer abgemeldet.
EWX_POWEROFF
Shuts down
the system and turns off the power.
The system
must support the power-off feature.
Windows
NT/2000/XP:
The calling
process must have the SE_SHUTDOWN_NAME privilege.
Fährt Windows
herunter und setzt den Computer in den StandBy-Modus,
sofern von der
Hardware unterstützt.
EWX_REBOOT
Shuts down
the system and then restarts the system.
Windows
NT/2000/XP: The calling process must have the SE_SHUTDOWN_NAME privilege.
Fährt Windows
herunter und startet es neu.
EWX_SHUTDOWN
Shuts down
the system to a point at which it is safe to turn off the power.
All file
buffers have been flushed to disk, and all running processes have stopped.
If the
system supports the power-off feature, the power is also turned off.
Windows
NT/2000/XP: The calling process must have the SE_SHUTDOWN_NAME privilege.
Fährt Windows
herunter.
EWX_FORCE
Forces
processes to terminate. When this flag is set,
the system
does not send the WM_QUERYENDSESSION and WM_ENDSESSION messages.
This can
cause the applications to lose data.
Therefore,
you should only use this flag in an emergency.
Die aktiven
Prozesse werden zwangsweise und ohne Rückfrage beendet.
EWX_FORCEIFHUNG
Windows
2000/XP: Forces processes to terminate if they do not respond to the
WM_QUERYENDSESSION
or WM_ENDSESSION message. This flag is ignored if EWX_FORCE is used.
Windows 2000/XP:
Die aktiven Prozesse werden aufgefordert, sich selbst zu beenden und
müssen dies
bestätigen. Reagieren sie nicht, werden sie zwangsweise beendet.
