C# Signature:

/// <summary>
/// This function is to be called twice.  
/// First time is to get pCount (function returns false with WinErr 122).  
/// Second Time is to get pointer of array (function returns true if successful)
/// Unfortunately this function cannot be used on another machine, unlike [winsta.dll] -> WinStationQueryInformationW ... see Cassia source code for details
/// </summary>
/// <param name="hServer"> Remote Server Handle not supported.  Value must be IntPtr.Zero ( WTS_CURRENT_SERVER_HANDLE ) </param>
/// <param name="pReserved">Value must be IntPtr.Zero</param>
/// <param name="Reserved">Always set to 0</param>
/// <param name="pListeners">A pointer to an array, filled when pCount is greater than 0</param>
/// <param name="pCount">If pListeners is IntPtr.Zero and pCount is 0, calling function will populate pCount</param>
/// <returns></returns>
