CMSPStream::ProcessGraphEvent method (mspstrm.h)
The ProcessGraphEvent method is called by the MSPCall object to let the stream handle graph events. The default implementation returns S_OK and does nothing. Derived MSPs must override this method if they want to propagate graph events to the application or take some other action in response to graph events.
