Shutting Down

You can use the ExitWindowsEx function to shut down the system. Shutting down flushes file buffers to disk and brings the system to a condition in which it is safe to turn off the computer.


The following example enables the SE_SHUTDOWN_NAME privilege and then shuts down the system.

BOOL MySystemShutdown()
{
   HANDLE hToken;
   TOKEN_PRIVILEGES tkp;

   // Get a token for this process.

   if (!OpenProcessToken(GetCurrentProcess(),
        TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
      return( FALSE );

   // Get the LUID for the shutdown privilege.

   LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,
        &tkp.Privileges[0].Luid);

   tkp.PrivilegeCount = 1;  // one privilege to set    
   tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

   // Get the shutdown privilege for this process.

   AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
        (PTOKEN_PRIVILEGES)NULL, 0);

   if (GetLastError() != ERROR_SUCCESS)
      return FALSE;

   // Shut down the system and force all applications to close.

   if (!ExitWindowsEx(EWX_SHUTDOWN | EWX_FORCE, 0))
      return FALSE;

   return TRUE;
}
