Detailed Description

<<extension>> Information about the status dds::core::status::StatusMask::service_request_accepted()

Currently, the only service that causes the ServiceRequestAcceptedStatus to be triggered is the rti::sub::TopicQuery service. A rti::topic::ServiceRequest is accepted when a dds::pub::DataWriter matches with a dds::sub::DataReader that has created a rti::sub::TopicQuery.

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