This method of the IExternalConnectionSink Interface notifies the object that a connection has been released. Both exconn and reserved correspond to the similarly named parameters of the IExternalConnection::AddConnection method.
public void OnReleaseConnection(int exconn, int reserved, boolean fLastReleaseCloses, int refcount);
Caution The value of refcount is advisory only; it is guaranteed to be zero if and only if the last external lock on the object has been released. However, refcount can be printed out for diagnostic purposes.
exconn | The type of external connection. |
reserved | Used by ActiveX to pass connection information. |
refcount | The new reference count of the COM proxy. |
fLastReleaseCloses | If set to true and if refcount is zero, the close action for the object is initiated. |
