Getting remote UDP peer address and port using getpeername()?

Question

Will getpeername() return the IP address info of the remote UDP peer ? I suspect that it is not going to work as it requires connection.

Please confirm whether getpeername() can be used to get the remote UDP peer address.

Answer 1

If a UDP socket isn't connected there is no peer. So there can't be a peer name.

And if it is connected, you already know who you connected it to.
