Call this function to establish a connection between a source, specified by pUnkSrc, and a sink, specified by pUnkSink.
BOOL AFXAPI AfxConnectionAdvise( LPUNKNOWN pUnkSrc, REFIID iid, LPUNKNOWN pUnkSink, BOOL bRefCount, DWORD FAR* pdwCookie );
A pointer to the object that calls the interface.
A pointer to the object that implements the interface.
The interface ID of the connection.
TRUE indicates that creating the connection should cause the reference count of pUnkSink to be incremented. FALSE indicates that the reference count should not be incremented.
A pointer to a DWORD where a connection identifier is returned. This value should be passed as the dwCookie parameter to AfxConnectionUnadvise when disconnecting the connection.
Nonzero if a connection was established; otherwise 0.
