I remember I have read the article about ros client’s register callback and action callback design in ros document. It discusses different ways to register the callback and run callback. Also, it can use poller to get callbacks to run or use trigger to run callbacks. I want to find it.

can you take a look at https://discourse.ros.org/t/where-is-the-discauss-of-register-callback-and-run-callback/34136.

i think it is not recommended to post the same questions on multiple site...
