Detailed Description

QoS policies supported by a DDSDataWriter entity.

You must set certain members in a consistent manner:

- DDS_DataWriterQos::history.depth <= DDS_DataWriterQos::resource_limits.max_samples_per_instance

- DDS_DataWriterQos::resource_limits.max_samples_per_instance <= DDS_DataWriterQos::resource_limits.max_samples

- DDS_DataWriterQos::resource_limits.initial_samples <= DDS_DataWriterQos::resource_limits.max_samples

- DDS_DataWriterQos::resource_limits.initial_instances <= DDS_DataWriterQos::resource_limits.max_instances

- length of DDS_DataWriterQos::user_data.value <= DDS_DomainParticipantQos::resource_limits .writer_user_data_max_length

If any of the above are not true, DDSDataWriter::set_qos and DDSDataWriter::set_qos_with_profile and DDSPublisher::set_default_datawriter_qos and DDSPublisher::set_default_datawriter_qos_with_profile will fail with DDS_RETCODE_INCONSISTENT_POLICY and DDSPublisher::create_datawriter and DDSPublisher::create_datawriter_with_profile and will return NULL.

Entity:

DDSDataWriter
