BOOL AFXAPI AfxConnectionUnadvise(
   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.
iid
The interface ID of the connection point interface.
bRefCount
TRUE indicates that disconnecting the connection should cause the reference count of pUnkSink to be decremented. FALSE indicates that the reference count should not be decremented.
dwCookie

Return Value

Nonzero if a connection was disconnected; otherwise 0.

Example

//m_pSink is a ptr to CCmdTarget-derived class supporting automation.
//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().
//m_dwCookie is a value obtained through AfxConnectionAdvise().
AfxConnectionUnadvise(m_pUnkSrc, IID_MYEVENT, pUnkSink, FALSE,
   m_dwCookie);
