Detailed Description

QoS policies supported by a DDS::DataWriter 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, DDS::DataWriter::set_qos and DDS::DataWriter::set_qos_with_profile and DDS::Publisher::set_default_datawriter_qos and DDS::Publisher::set_default_datawriter_qos_with_profile will fail with DDS::Retcode_InconsistentPolicy and DDS::Publisher::create_datawriter and DDS::Publisher::create_datawriter_with_profile and will return NULL.

Entity:
DDS::DataWriter
