jonathan@jvc.UUCP (Jonathan Hue) (03/29/89)
Since ofiles (recently posted to comp.sources.unix) doesn't support SunOS 3.5,
here is my attempt at getting it to work. A slightly different getuser() is
needed, so I just stole it from "top". I also added an #ifdef DIRS_NOT_DEVS,
if you want the cwd to come out as the inode for the directory, not the
inode of the device in /dev it lives on. You can just cc -O -o ofiles ofiles.c
on a machine running 3.5 and it should work (define DIRS_NOT_DEVS if you
want to). It should still work on 4.0 if you add a -DsunOS4, but we don't
have it, so it's not tested.
