Retrieves the DDS_TopicQueryData data contained in the specified DDS_ServiceRequest.
This operation will extract the content from the request body of the DDS_ServiceRequest and place it into the specified DDS_TopicQueryData object.
The specified DDS_ServiceRequest must be a valid sample associated with the service id DDS_TOPIC_QUERY_SERVICE_REQUEST_ID. Otherwise this operation will return DDS_BOOLEAN_FALSE.
This operation can be called within the context of a DDSDataWriterListener::on_service_request_accepted to retrieve the DDS_TopicQueryData of a DDS_ServiceRequest that has been received with service id DDS_TOPIC_QUERY_SERVICE_REQUEST_ID
topic_query_data | <<inout>> A DDS_TopicQueryData object where the content from the service request is extracted. |
service_request | <<in>> Input DDS_ServiceRequest that contains the DDS_TopicQueryData as part of its request body. |
