Detailed Description

QoS policies supported by a DDS_Topic 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, DDS_Topic_set_qos, DDS_Topic_set_qos_with_profile and DDS_DomainParticipant_set_default_topic_qos will fail with DDS_RETCODE_INCONSISTENT_POLICY and DDS_DomainParticipant_create_topic will return NULL.

Entity:
DDS_Topic
