IMediaEvent::FreeEventParams
Frees resources associated with the parameters of an event.
HRESULT FreeEventParams(
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 Values
Returns an HRESULT value.
Remarks
Event parameters can be of type LONG or BSTR. If a BSTR is 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::GetEvent because these cannot be overridden by IMediaEvent::CancelDefaultHandling. Therefore, this method is not used to release interfaces.
