DDS_Boolean DDS_DataWriterShmemRefTransferModeSettings::enable_data_consistency_check

Controls if samples can be checked for consistency.

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

[default] DDS_BOOLEAN_TRUE
