Working with publishers.

Setting up a publisher

• Set up participant
• Create a DDSPublisher

  DDS_PublisherQos publisher_qos;
   
  // MyPublisherListener is user defined and 
  // extends DDSPublisherListener
  DDSPublisherListener* publisher_listener = 
          =                     new MyPublisherListener(); // or = NULL
   
  participant->get_default_publisher_qos(publisher_qos);
   
  DDSPublisher* publisher = participant->create_publisher(publisher_qos, 
                                                     publisher_listener,
                                                    DDS_STATUS_MASK_ALL);
  if (publisher == NULL) {
      // ... error 
   
  };

Tearing down a publisher

• Delete DDSPublisher:

  DDS_ReturnCode_t retcode;
   
  retcode = participant->delete_publisher(publisher);
   
  if (retcode != DDS_RETCODE_OK) {
      // ... check for cause of failure
  }
