  long 
lEventCode,
  long 
lParam1,
  long 
lParam2
);

Parameters

lEventCode

[in] Next event notification.

lParam1

[in] First parameter of the event.

lParam2

[in] Second parameter of the event.

Return Value

Returns an HRESULTvalue.

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.
