Publication Example
/* Foo_publisher.cxx
A publication of data of type MyOtherType
This file is derived from code automatically generated by the rtiddsgen
rtiddsgen -language C++11 -example <arch> Foo.idl
Example publication of type MyOtherType automatically generated by
'rtiddsgen'. To test them follow these steps:
(1) Compile this file and the example subscription.
(2) Start the subscription on the same domain used for RTI Data Distribution
Service with the command
objs/<arch>/Foo_subscriber <domain_id> <sample_count>
(3) Start the publication on the same domain used for RTI Data Distribution
Service with the command
objs/<arch>/Foo_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.
To run the example application on domain <domain_id>:
On Unix:
objs/<arch>/Foo_publisher <domain_id>
objs/<arch>/Foo_subscriber <domain_id>
On Windows:
objs<arch>\Foo_publisher <domain_id>
objs<arch>\Foo_subscriber <domain_id>
#include <iostream>
#include <dds/pub/ddspub.hpp>
#include <rti/util/util.hpp> // for sleep()
#include "Foo.hpp"
void publisher_main(int domain_id, int sample_count)
// Create a DomainParticipant with default Qos
dds::domain::DomainParticipant participant (domain_id);
// Create a Topic -- and automatically register the type
dds::topic::Topic<MyOtherType> topic (participant, "Example MyOtherType");
// Create a DataWriter with default Qos (Publisher created in-line)
MyOtherType sample;
for (int count = 0; count < sample_count || sample_count == 0; count++) {
// Modify the data to be written here
std::cout << "Writing MyOtherType, count " << count << std::endl;
int main(int argc, char *argv[])
int domain_id = 0;
int sample_count = 0; // infinite loop
if (argc >= 2) {
domain_id = atoi(argv[1]);
if (argc >= 3) {
sample_count = atoi(argv[2]);
// To turn on additional logging, include <rti/config/Logger.hpp> and
// uncomment the following line:
// rti::config::Logger::instance().verbosity(rti::config::Verbosity::STATUS_ALL);
try {
publisher_main(domain_id, sample_count);
} catch (const std::exception& ex) {
// This will catch DDS exceptions
std::cerr << "Exception in publisher_main(): " << ex.what() << std::endl;
return -1;
// RTI Connext provides a finalize_participant_factory() method
// if you want to release memory used by the participant factory singleton.
// Uncomment the following line to release the singleton:
// dds::domain::DomainParticipant::finalize_participant_factory();
return 0;
