Field Documentation

DDS_UnsignedLong DDS_DataWriterProtocolQosPolicy::rtps_object_id

The RTPS Object ID.

This value is used to determine the RTPS object ID of a data writer according to the DDS-RTPS Interoperability Wire Protocol.

Only the last 3 bytes are used; the most significant byte is ignored.

[default] DDS_RTPS_AUTO_ID

[range] [0,0x00ffffff]

struct DDS_RtpsReliableWriterProtocol_t DDS_DataWriterProtocolQosPolicy::rtps_reliable_writer

The reliable protocol defined in RTPS.

[default] heartbeat_period 3.0 seconds;
heartbeats_per_max_samples: 1;
max_send_window: minimum(256, ::DDS_HistoryQosPolicy::depth * ::DDS_ResourceLimitsQosPolicy::max_instances);
max_heartbeat_retries: DDS_LENGTH_UNLIMITED;
first_write_sequence_number: {0,1};
