Detailed Description

QoS policies supported by a DDSTopic entity.

You must set certain members in a consistent manner:

length of DDS_TopicQos::topic_data .value <= DDS_DomainParticipantQos::resource_limits .topic_data_max_length

If any of the above are not true, DDSTopic::set_qos, DDSTopic::set_qos_with_profile and DDSDomainParticipant::set_default_topic_qos will fail with DDS_RETCODE_INCONSISTENT_POLICY and DDSDomainParticipant::create_topic will return NULL.

Entity:
DDSTopic

QoS Policies allowed ranges within each Qos.
