Hey @DLu, can you double check if these values are specific to different DDS implementations?

Honestly, if someone wants to do that they can, but otherwise it just seems like a roadblock to getting better documentation.

INFINITE is rmw dependent definition as below. and ROS 2 just handles that as INFINITE but exact digits.

  • rmw_fastrtps to Fast-DDS

  • Fast-DDS to rmw_fastrtps
