Detailed Description

QoS policies supported by a DDS_DomainParticipant entity.

Certain members must be set in a consistent manner:

Length of DDS_DomainParticipantQos::user_data .value <= DDS_DomainParticipantQos::resource_limits .participant_user_data_max_length

For DDS_DomainParticipantQos::discovery_config .publication_writer
high_watermark <= DDS_DomainParticipantQos::resource_limits .local_writer_allocation .max_count heartbeats_per_max_samples <= DDS_DomainParticipantQos::resource_limits .local_writer_allocation.max_count

For DDS_DomainParticipantQos::discovery_config .suscription_writer
high_watermark <= DDS_DomainParticipantQos::resource_limits .local_reader_allocation.max_count heartbeats_per_max_samples <= DDS_DomainParticipantQos::resource_limits .local_reader_allocation.max_count

If any of the above are not true, DDS_DomainParticipant_set_qos and DDS_DomainParticipant_set_qos_with_profile and DDS_DomainParticipantFactory_set_default_participant_qos will fail with DDS_RETCODE_INCONSISTENT_POLICY, and DDS_DomainParticipantFactory_create_participant will fail.
