ONE intent. "Moving" files/directories around is even possible on file
systems of operating systems which don't support hardlinks at all (e.g.
<I don't say it>). The advantage of (hard) links is that a file may be
accessed via different paths. It's really annoying when I want to
delete a file out of *MY* home directory and I can't do so because
another user has invoked a "list" on it (via another "hardlink").

(2) pls. see above ...

(1)
Fine! I'm waiting eagerly for it:

  mktemp(fn);
  fd = creat(fn, S_IWRITE);
  unlink(fn);

  write(fd, ...);
  ...
  close(fd);

  is a really nice way to create and remove temp files ...

Yours,
