DWORD WDSTCIAPI WdsTransportClientStartSession( HANDLE hSessionKey );
The handle returned by the WdsTransportClientInitializeSession session.
If the function succeeds, the return value is ERROR_SUCCESS.
All callbacks must be registered before this function is called. If a required callback is not registered, this function will fail.
It is possible for a session to start and complete before this function returns. This means that it is possible to receive a callback with a session handle that has not been seen yet. This also means that a session can start and error out before this function has a chance to complete. In this case, this function may still return success, even if the session itself fails.
