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 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 */
  }
