   LPUNKNOWN pUnkSrc,
   REFIID iid,
   LPUNKNOWN pUnkSink,
   BOOL bRefCount,
   DWORD dwCookie 
);

Parameters

pUnkSrc

A pointer to the object that calls the interface.

pUnkSink

A pointer to the object that implements the interface.

//Get a pointer to sinks IUnknown, no AddRef done.
LPUNKNOWN pUnkSink = m_pSink->GetIDispatch(FALSE);

//Terminate a connection between source and sink.
//m_pUnkSrc is IUnknown of server obtained by CoCreateInstance().
