/* deadline_contentfilter_publisher.c

   A publication of data of type deadline_contentfilter

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

   rtiddsgen -language C -example <arch> deadline_contentfilter.idl

   Example publication of type deadline_contentfilter 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>/deadline_contentfilter_subscriber <domain_id> <sample_count>

   (3) Start the publication with the command
       objs/<arch>/deadline_contentfilter_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>:

       On Unix:

       objs/<arch>/deadline_contentfilter_publisher <domain_id>
       objs/<arch>/deadline_contentfilter_subscriber <domain_id>

       On Windows:

       objs\<arch>\deadline_contentfilter_publisher <domain_id>
       objs\<arch>\deadline_contentfilter_subscriber <domain_id>
