Requesting Acknowledgment
If the reply_tag parameter is not NULL, an acknowledgment will be sent for the Adapter::beginTransaction event. The tag field will be set in reply_tag so that your application can correlate the acknowledgment event you receive with the Adapter::beginTransaction event that was published.
Note:
The acknowledgment reply will not be sent until the adapter receives the first request event.
