Built-in topic block normal pub/sub data

Hi,

I add a function to get DDS_ParticipantBuiltinTopicData in the HelloWorld_dpde example. So the basic steps are:

 1. Print new found participant info (e.g. DCPS key) by install the listenser :

builtin_participant_listener.on_data_available = BuiltinParticipantListener_on_data_available;

retcode = DDS_DataReader_set_listener( builtin_participant_datareader, &builtin_participant_listener, DDS_DATA_AVAILABLE_STATUS);

2. Start normal Pub/Sub workflow:

How to get ParticipantBuiltinTopic Info

Hi,

 

I'm using RTI DDS Micro and trying to get the ParticipantBuiltinTopic information. I found some previous topics about the ParticipantBuiltinTopic, but seems all of them were working on the RTI DDS Pro. I'm wondering:

(1) Is it the same to get the ParticipantBuiltinTopic info on both DDS Micro and DDS Pro? I checked the C API manual for both products and the data structure looks the same.
