Function signature to handle an event for the pad.

This variant is for specific elements that will take into account the last downstream flow return (from a pad push), in which case they can return it.

alias GstPadEventFullFunction = GstFlowReturn function(GstPad* pad, GstObject* parent, GstEvent* event)

Return Value

GST_FLOW_OK if the event was handled properly, or any other GstFlowReturn dependent on downstream state.
