|
* @param reason will be set to the policy id of one of the mismatching QoS, or to DDS_INVALID_QOS_POLICY_ID if there is no mismatch or if the mismatch is in topic or type name (those are not really QoS and don't have a policy id)

|
|
* @param rd_typeid_req_lookup is set to true in case the matching cannot be completed because of missing type information. A type-lookup request is required to get the details of the type to do the qos matching (e.g. check assignability)
