Detailed Description

DDS_SERVICE_REQUEST_ACCEPTED_STATUS

Currently, the only service that causes the ServiceRequestAcceptedStatus to be triggered is the DDSTopicQuery service. A DDS_ServiceRequest is accepted when a DDSDataWriter matches with a DDSDataReader that has created a DDSTopicQuery.

This status is also changed (and the listener, if any, called) when a ServiceRequest has been cancelled, or deleted. This will happen when a DDSDataReader deletes a TopicQuery using DDSDataReader::delete_topic_query.
