<<cert>> DDS_LIVELINESS_LOST_STATUS

Entity:

Field Documentation

DDS_Long DDS_LivelinessLostStatus::total_count

Total cumulative number of times that a previously-alive DDS_DataWriter became not alive due to a failure to to actively signal its liveliness within the offered liveliness period.

This count does not change when an already not alive DDS_DataWriter simply remains not alive for another liveliness period.

DDS_Long DDS_LivelinessLostStatus::total_count_change

The incremental changees in total_count since the last time the listener was called or the status was read.
