TCPSocket usage questions

Hi there,

I'm hoping someone can clarify something or explain why it's not needed. I'm trying to get my head round socket programming and have a few questions. My use case is to have a server listening on a port for a single connection which sends commands and receives responses. So I have no need for multiple connections, just be robust in respect to the network going down.

If I've got a TCPSocket that I've opened, bound and called listen on, once I've accepted a new connection, how do I get the status of the parent socket? I've been trying to adapt the example at the bottom of the the following page and use a similar method with an event handler for sigio(): https://os.mbed.com/docs/mbed-os/v5.11/apis/network-socket.html

However, I can't find any documentation or examples for polling or responding to state changes on the parent socket. Perhaps it never does anything aside from create children?

Thanks.
