CMSPStream::ProcessGraphEvent method (mspstrm.h)

  • Article

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.

HRESULT ProcessGraphEvent(
  long     lEventCode,
  LONG_PTR lParam1,
  LONG_PTR lParam2
);

Parameters
