SetProcessShutdownParameters

The SetProcessShutdownParameters function sets shutdown parameters for the currently calling process. This function sets a shutdown order for a process relative to the other processes in the system.

BOOL SetProcessShutdownParameters(

DWORD dwLevel,
// shutdown priority
DWORD dwFlags
// shutdown flags
);

Parameters

dwLevel

Specifies the shutdown priority for a process relative to other processes in the system. The system shuts down processes from high dwLevel values to low. The highest and lowest shutdown priorities are reserved for system components. This parameter must be in the following range of values:

Value
Meaning
000pics/WIN3200090000.gif0FF
System reserved last shutdown range.
100pics/WIN3200090000.gif1FF
Application reserved last shutdown range.
200pics/WIN3200090000.gif2FF
Application reserved "in between" shutdown range.
300pics/WIN3200090000.gif3FF
Application reserved first shutdown range.
400pics/WIN3200090000.gif4FF
System reserved first shutdown range.

All processes start at shutdown level 0x280.

dwFlags

Specifies a flags parameter. It can be the following value:

Value
Meaning
SHUTDOWN_NORETRY
Specifies whether to retry the shutdown if the specified time-out period expires. If this flag is specified, the system terminates the process without displaying a retry dialog box for the user.

Return Values

If the function is succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Remarks

Applications running in the system security context do not get shut down by the operating system. They get notified of shutdown or logoff through the callback function installable via SetConsoleCtrlHandler. They also get notified in the order specified by the dwLevel parameter.
