How to change the log output from version C to version C++?

[usstmiracle]

As for cyclonedds-cxx
Is there a similar log API and how should it be used?
Is there an example of how to use the C++version log

Is there a similar log API for cyclonedds cxx, and how should it be used? Is there an example of how to use the C++version log
