Detailed Description

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

Entity:

DDSDomainParticipant, DDSDataReader, DDSDataWriter

Properties:

RxO = NO;
Changeable = UNTIL ENABLE

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.
