Call this function to disconnect a connection between a source, specified by pUnkSrc, and a sink, specified by pUnkSink.
A pointer to the object that calls the interface.
A pointer to the object that implements the interface.
The interface ID of the connection point interface.
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.
The connection identifier returned by AfxConnectionAdvise.
Nonzero if a connection was disconnected; otherwise 0.
