Detailed Description

Instantiates DataReader < DDS_TopicBuiltinTopicData > .

DDSDataReader of topic DDS_TOPIC_TOPIC_NAME used for accessing DDS_TopicBuiltinTopicData of the remote DDSTopic.

Note: The DDS_TopicBuiltinTopicData built-in topic is meant to convey information about discovered Topics. This Topic's samples are not propagated in a separate packet on the wire. Instead, the data is sent as part of the information carried by other built-in topics (DDS_PublicationBuiltinTopicData and DDS_SubscriptionBuiltinTopicData). Therefore TopicBuiltinTopicData DataReaders will not receive any data.
