You should look at getsockopt(), getsockname(), etc... I'm pretty
sure that one of those will offer you exactly what you need. Also,
look at the error codes. Sometimes you can rely on them because you
have different types depending on whether the FD you point to is
not a socket or is a socket of invalid type.
