SetProcessShutdownParameters函数

# 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 options
    );

#### Parameters ####

*dwLevel*

\[in\] 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.

<table> 
 <tbody> 
  <tr> 
   <th align="left">Value</th> 
   <th align="left">Meaning</th> 
  </tr> 
  <tr> 
   <td>000–0FF</td> 
   <td>System reserved last shutdown range.</td> 
  </tr> 
  <tr> 
   <td>100–1FF</td> 
   <td>Application reserved last shutdown range.</td> 
  </tr> 
  <tr> 
   <td>200–2FF</td> 
   <td>Application reserved "in between" shutdown range.</td> 
  </tr> 
  <tr> 
   <td>300–3FF</td> 
   <td>Application reserved first shutdown range.</td> 
  </tr> 
  <tr> 
   <td>400–4FF</td> 
   <td>System reserved first shutdown range.</td> 
  </tr> 
 </tbody> 
</table>

All processes start at shutdown level 0x280.

*dwFlags*

\[in\] This parameter can be the following value.

<table> 
 <tbody> 
  <tr> 
   <th align="left">Value</th> 
   <th align="left">Meaning</th> 
  </tr> 
  <tr> 
   <td>SHUTDOWN_NORETRY</td> 
   <td>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.</td> 
  </tr> 
 </tbody> 
</table>

#### Return Values ####

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.

**Windows NT/2000/XP:** Included in Windows NT 3.1 and later.  
 **Windows 95/98/Me:** Unsupported.
