When your transactional client application publishes an event, the Broker places it in the event queue of each BrokerTxClient that has subscribed to that event type.

In order for your application to be able to publish an event, it must first create a BrokerTxClient, as described on Beginning a Transaction. Then, use the awTxBeginTransaction function to begin the transaction. Your application may then use the BrokerTxClient to create an event, as described on Setting Structure Fields. After setting the event fields, your application is ready to publish the event.
