Working with publishers. More...

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
    }
