3.6. Create Publisher

A publishing application needs to create a DDS Publisher and then a DataWriter for each Topic it wants to publish.

In RTI Connext DDS Micro, PublisherQos in general contains no policies that need to be customized, while DataWriterQos does contain several customizable policies.

• Create Publisher:

  DDS_Publisher *publisher = NULL;
  publisher = DDS_DomainParticipant_create_publisher(participant,
                                                     &DDS_PUBLISHER_QOS_DEFAULT,
                                                     NULL,
                                                     DDS_STATUS_MASK_NONE);
  if (publisher == NULL)
  {
      /* failure */
  }
