Hi, I'm trying to use function matched_publication_participant_data() to achive domain_partipant's name of matched publishers. But as modern c++ ducument said, if matched_publisher and data reader where in the same domain_participant, it will throw an exception. how can I know that the matched_publisher and data_reader are in the same domain_participant to don't use function matched_publication_participant_data() for that matched_publisher?
