The High Performance, Small Footprint DDS from Twin Oaks Computing, Inc

The DurablityQosPolicy controls the durablity of data. The DDS API identifies several degrees of data durability.
A DataWriter can offer to provide a level of durablity for data that it generates, and a DataReader requests the level of durability that it requires. If the DataReader requests a 'higher' level of durability than that offered by the DataWriter, then the QoS policy is incompatible.
CoreDX DDS currently supports VOLATILE and TRANSIENT_LOCAL.
