How to perform fast user switching

Question

I'm looking for a function that could perform a fast user switching. Something like ExitWindowsEx() or InitiateShutdown(). I searched in MSDN but I could find anything useful. The only thing was that: http://msdn.microsoft.com/en-us/library/windows/desktop/bb776893%28v=vs.85%29.aspx but there is nothing how to do it programically. Thanks in advance.

Fast User Switching is implemented via Remote Desktop Services (used to be called Terminal Services), so to initiate the switching screen it's simply a matter of disconnecting the current session:

WTSDisconnectSession(WTS_CURRENT_SERVER_HANDLE, WTS_CURRENT_SESSION, FALSE);
