The AppGen plugin is an implementation of the RTI Connext DDS Micro DDS_AppGen plugin interface and implements the application generation supported by RTI Connext DDS Micro. RTI Connext DDS Micro requires that a DDS_AppGen plugin is registered with the name "_mag" in the DomainParticipantFactory before a participant can be created. Each call to DDSDomainParticipantFactory::create_participant_from_config creates its own instance of the DDS_AppGen plugin. Please refer to the Getting Started Guide for an example of how to register the application generation factory.
