Looking at Winwlx.h it looks like you would just use the value directly:

	DWORD	dwDllVersion;
	WlxNegotiate( WLX_CURRENT_VERSION, &dwDllVersion );

Listed here in the remarks
http://msdn2.microsoft.com/en-us/library/aa380567.aspx

> LPWSTR lpWinsta=
		"Winsta0";
It is also listed as winsta0 and WinSta0 in other places.

> HANDLE hWlx=NULL;
> PVOID* pWlxContext;
	PVOID pWlxContext;

> MyWlxInitialize(lpWinsta,hWlx,pvReserved,pWinlogonFunctions,pWlxContext);
   WlxInitialize("Winsta0", hWlx, NULL, (void*)dwDllVersion, &pWlxContext);

But, after reading this
http://msdn.microsoft.com/msdnmag/issues/05/05/securitybriefs/
I think you would rather get pWlxContext from WinLogon somehow.

Simpler to write
	MyWlxLoggedOnSAS( pWlxContext, WLX_SAS_TYPE_CTRL_ALT_DEL, NULL);
