Detailed Description

Assigns a name and a role name to a DDSDomainParticipant, DDSPublisher, DDSSubscriber, DDSDataWriter or DDSDataReader. Except for DDSPublisher and DDSSubscriber, these names will be visible during the discovery process and in RTI tools to help you visualize and debug your system.

Usage

The name and role name can only be 255 characters in length.

The strings must be null-terminated strings allocated with DDS_String_alloc or DDS_String_dup.

If you provide a non-null pointer when getting the QoS, then it should point to valid memory that can be written to, to avoid ungraceful failures.
