Summary: The ExitWindowsEx API
!!!!C# Signature:
 [DllImport("user32.dll", SetLastError = true)]
 [return: MarshalAs(UnmanagedType.Bool)]
 static extern bool ExitWindowsEx(ExitWindows uFlags, ShutdownReason dwReason);
!!!!Alternative C# Signature:
 [DllImport("user32.dll", SetLastError = true)]
 [return: MarshalAs(UnmanagedType.Bool)]
 static extern bool ExitWindowsEx(uint uFlags, uint dwReason);
!!!!VB Signature:
 <DllImport("user32.dll", SetLastError:=True)> _
 Shared Function ExitWindowsEx( _
     ByVal uFlags As ExitWindows, _
     ByVal dwReason As ShutdownReason) As <MarshalAs(UnmanagedType.Bool)> Boolean
 End Function
!!!!Alternative VB Signature:
 Declare Function ExitWindowsEx Lib "user32" (ByVal dwOptions As Int32, ByVal dwReserved As Int32) As Int32
!!!!User-Defined Types:
None.

!!!!Notes:
Parameters:
	*uFlags - See Enums.ExitWindows							
	*dwReason - See Enums.ShutdownReason		
!!!!Tips & Tricks:
To shut down or restart the system on NT/2K/XP, the calling process must use the AdjustTokenPrivileges function to enable the SE_SHUTDOWN_NAME privilege.

If uFlags is set to 'LogOff', then the call will fail if the process calling it is a non-interactive-process (i.e a Windows Service). Read the ExitWindowsEx@msdn on MSDN for more info. All other values for uFlags work fine for non-interactive-processes.

!!!!Sample Code:

class Class1
	{
		[DllImport("user32.dll")]
		static extern bool ExitWindowsEx(uint uFlags, uint dwReason);

[STAThread]
		static void Main(string[] args)
		{
			ExitWindowsEx(ExitWindows.LogOff, ShutdownReason.MajorOther | ShutdownReason.MinorOther); 
			//this will cause the computer to logoff.
		}
	}

!!!!Alternative Managed API:
Do you know one?  Please contribute it!

Documentation: ExitWindowsEx@msdn on MSDN

!!!!Page Change:
Changed the sample code Reason parameter from "&" to "ShutdownReason.MajorOther | ShutdownReason.MinorOther". Amperstand (&) is the binary AND condition, and the values ANDed together would be zero. The intended condition is that the flags be ORed together. (|)
