I have a socket that is set up to listen()
Normally I would accept() these connections based on a file descriptor being ready via select(). Can I change this to be a recv() instead of accept(), with that same file descriptor?

No, they’re not interchangeable.
You’re only listening on a single file descriptor using
select, but you want have a file descriptor per connection once you have connected clients.acceptextracts the first connection request on the queue of pending connections for the listening socket, creates a new connected socket, and returns a new file descriptor referring to that socket.Once you have that new file descriptor, you can use recv to receive data from the client on it.
