For example, I'm typing this on an Intel Mac running Mac OS 10.5.4,
and 'man sendfile' shows
      sendfile -- send a file to a socket
and claims that it is checked runtime error if the destination is
anything but a socket.

It looks as though file -> socket is the only moderately portable
case, and of course systems without can fake it by a sequence of
reads and writes.
