How does nginx worker process share the 'liste

Question

This http://aosabook.org/en/nginx.html says that "worker processes accept new requests from a shared ""listen" socket and execute a highly efficient run-loop inside each

I looked at hte code but did not understand how the socket is shared. Is it the case that the master process creates a listen queue, binds and then forks. In that case, how does the OS decide which worker process to hand over the incoming connection to? Is it round robin or random? I am assuming that different OS may have different policies

Answer 1

In that case, how does the OS decide which worker process to hand over the incoming connection to?

The question sounds exactly like "how does the OS decide which process will get to run".
