   A publication of data of type profiles

   This file is derived from code automatically generated by the rtiddsgen 
   command:

   rtiddsgen -language C# -example <arch> profiles.idl

   Example publication of type profiles automatically generated by 
   'rtiddsgen'. To test them follow these steps:

   (1) Compile this file and the example subscription.

   (2) Start the subscription with the command
       objs\<arch>\profiles_subscriber <domain_id> <sample_count>
                
   (3) Start the publication with the command
       objs\<arch>\profiles_publisher <domain_id> <sample_count>

   (4) [Optional] Specify the list of discovery initial peers and 
       multicast receive addresses via an environment variable or a file 
       (in the current working directory) called NDDS_DISCOVERY_PEERS. 

   You can run any number of publishers and subscribers programs, and can 
   add and remove them dynamically from the domain.


   Example:

       To run the example application on domain <domain_id>:

       bin\<Debug|Release>\profiles_publisher <domain_id> <sample_count>
       bin\<Debug|Release>\profiles_subscriber <domain_id> <sample_count>

         *
         * 1) Creating a file named USER_QOS_PROFILES.xml, which is loaded,

         * volatile DataWriters and DataReaders.
         *
         * 2) Adding XML documents to the DomainParticipantFactory using its
         * Profile QoSPolicy (DDS Extension). In this case, we add
         * my_custom_qos_profiles.xml to the url_profile sequence, which stores
         * the URLs of all the XML documents with QoS policies that are loaded 
         * by the DomainParticipantFactory aside from the ones that are 
         * automatically loaded.
         * my_custom_qos_profiles.xml defines a QoS profile named
         * transient_local_profile that configures reliable, transient local
         * DataWriters and DataReaders.
