:How about testing with stat(2) that an argument is a socket
:thus eliminating the need to open(2) sockets and connect(2)
:to non-sockets?
I don't see any particular reason why. An open() failure is as fast
or faster then stat(). If it fails and we get the appropriate errno,
we try a connect(). Either connect() is supported or it isn't. If it
is a case of a missing file we don't try the connect() because we get
a different errno. I see no particular need to stat the path, no ill
effects will occur if the connect() fails.
