2.7. Create Publisher

A DDS Publisher contains zero or more DataWriters. A publishing application must create at least one DDS Publisher and then a DataWriter for each Topic it wants to publish.

Please refer to PublisherQos and DataWriterQos for customizable policies for these DDS entities.

• 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 */
  }
