- lParam2

Remarks
Event parameters can be of type LONGor BSTR. If a BSTRis passed as an event, it will have been allocated by the task allocator and should be freed using this method. No reference-counted interfaces are passed to an application using IMediaEvent::GetEventbecause these cannot be overridden by IMediaEvent::CancelDefaultHandling. Therefore, this method is not used to release interfaces.
