Create Publisher
================

.. highlight:: c

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

In |me|, :link_connextmicro_dds_api_c_up_one:`PublisherQos <structDDS__PublisherQos.html>` in general contains no policies that need to be
customized, while :link_connextmicro_dds_api_c_up_one:`DataWriterQos <structDDS__DataWriterQos.html>` 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 */
    }
