IConnector::IsConnected method (devicetopology.h)
The IsConnected method indicates whether this connector is connected to another connector.
HRESULT IsConnected( BOOL *pbConnected );

If the method succeeds, it returns S_OK. If it fails, possible return codes include, but are not limited to, the values shown in the following table.
