Detailed Description

QoS policies supported by a DDS::DataReader entity.

You must set certain members in a consistent manner:

DDS::DataReaderQos::deadline .period >= DDS::DataReaderQos::time_based_filter .minimum_separation

DDS::DataReaderQos::history .depth <= DDS::DataReaderQos::resource_limits .max_samples_per_instance

DDS::DataReaderQos::resource_limits .max_samples_per_instance <= DDS::DataReaderQos::resource_limits .max_samples DDS::DataReaderQos::resource_limits .initial_samples <= DDS::DataReaderQos::resource_limits .max_samples

DDS::DataReaderQos::resource_limits .initial_instances <= DDS::DataReaderQos::resource_limits .max_instances

DDS::DataReaderQos::reader_resource_limits .initial_remote_writers_per_instance <= DDS::DataReaderQos::reader_resource_limits .max_remote_writers_per_instance

DDS::DataReaderQos::reader_resource_limits .initial_infos <= DDS::DataReaderQos::reader_resource_limits .max_infos

DDS::DataReaderQos::reader_resource_limits .max_remote_writers_per_instance <= DDS::DataReaderQos::reader_resource_limits .max_remote_writers

DDS::DataReaderQos::reader_resource_limits .max_samples_per_remote_writer <= DDS::DataReaderQos::resource_limits .max_samples

length of DDS::DataReaderQos::user_data .value <= DDS::DomainParticipantQos::resource_limits .reader_user_data_max_length

If any of the above are not true, DDS::DataReader::set_qos and DDS::DataReader::set_qos_with_profile will fail with DDS::Retcode_InconsistentPolicy and DDS::Subscriber::create_datareader will return NULL.
