I am not sure I understand your question. Are you asking about the implementation of libuv, or how to use it to achieve a certain goal, or something else?

This is not a super polished response. I'm hoping it's enough to help you get started and reach a better understanding of the code. > (1) Who put callback function...

In `threadpool.c`, the `worker` function (thread) issues `uv_async_send(&w->loop->wq_async)` whenever it completes work. This wakes up the event loop, which calls the async handler's callback from the event loop. This callback...
