Method processEventCallback

internal/etw/trace.go:410–419

processEventCallback is the event callback function signature that is called each time a new event is available on the session buffer. It does the heavy lifting of parsing incoming ETW events from raw data buffers, building the state machine, and pushing events to the channel.

(ev *etw.EventRecord)

// a new event is available on the session buffer. It does the heavy lifting of parsing incoming
// ETW events from raw data buffers, building the state machine, and pushing events to the channel.
func (t *Trace) processEventCallback(ev *etw.EventRecord) uintptr {
	if t.consumer == nil {
		panic("consumer is nil")
	}
	if err := t.consumer.ProcessEvent(ev); err != nil {
		t.errs <- err
		eventsFailed.Add(err.Error(), 1)
	}
	return callbackNext
}

// bufferStatsCallback is periodically triggered by ETW subsystem for the purpose of reporting
// buffer statistics, such as the number of buffers processed.
