Enumerator
DDS_BEST_EFFORT_RELIABILITY_QOS	Indicates that it is acceptable not to retry the propagation of any samples. Presumably new values for the samples are generated often enough that it is not necessary to re-send or acknowledge any samples. [default]
DDS_RELIABLE_RELIABILITY_QOS	Specifies that RTI Connext DDS Micro will attempt to deliver all samples in its history. Missed samples may be retried. In steady state, when no modifications are communicated via the DDS_DataWriter, the middleware guarantees that all samples in the DDS_DataWriter history will eventually be delivered to all the DDS_DataReader objects, subject to timeouts that indicate a loss of communication with a particular DDS_Subscriber. Outside steady state the HISTORY and RESOURCE_LIMITS policies will determine how samples become part of the history and whether samples can be discarded from it. Note The RTPS spec defines reliability as 0x03 to comply with the RTPS specification. However, RTI Connext Core uses 0x3, as well as others.
