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.

Syntax

C++

BOOL WINAPI SetProcessShutdownParameters(
  _In_ DWORD dwLevel,
  _In_ DWORD dwFlags
);

Parameters

dwLevel [in]

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
000-0FF	System reserved last shutdown range.
100-1FF	Application reserved last shutdown range.
200-2FF	Application reserved "in between" shutdown range.
300-3FF	Application reserved first shutdown range.
400-4FF	System reserved first shutdown range.

All processes start at shutdown level 0x280.

dwFlags [in]

This parameter can be the following value.

Value	Meaning
SHUTDOWN_NORETRY 0x00000001	The system terminates the process without displaying a retry dialog box for the user.

Return value

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

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

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.
