Field Documentation

DDS_Boolean DDS_DataWriterShmemRefTransferModeSettings::enable_data_consistency_check

Controls if samples can be checked for consistency.

When this setting is true, the DDS_DataWriter sends an incrementing sequence number as an inline QoS with every sample. This sequence number allows a DDS_DataReader to use the FooDataReader_is_data_consistent API to detect if the DDS_DataWriter overwrote the sample before the DDS_DataReader could complete processing the sample.

[default] DDS_BOOLEAN_TRUE
