The subsequent several chapters are meant to bolster your Essentials and prepare a Basis before you can generate Server and Consumer applications employing socket. Should you immediately want to jump to check out how to write down a client and server program, You'll be able to do so but It's not at all advised.

A socket to be used with the AF_IRDA address family can only be made If your community Computer system has an infrared port and driver set up.
