    I hate to be a pedantic ***, but the C language itself
    doesn't have sockets nor ports. It is, in a way, quite a
    boring language. The POSIX C language bindings, on the other
    hand, have ports and sockets. It might not be a very important
    distinction for many, but if you know what's what, then it'll be
    easier to port the code to non-POSIX platforms.
