This status is the reciprocal status to the DDS_LivelinessChangedStatus on the reader. It is different than the DDS_LivelinessLostStatus on the writer in that the latter informs the writer about its own liveliness; this status informs the writer about the "liveliness" (activity) of its matched readers.
All counts in this status will remain at zero for best effort writers.
