I have a sun system, running SunOS 4.0.3, and I would like to be able to tell when a terminal (/dev/ttyp?) has a user logged in to it, via an ioctl. This is because when dump(8) with the n flag tries to notify all operators that the dump is done, it looks in utmp, which often has entries which are out of date. Dump then tries to fopen the tty (which has no one logged in) and hangs forever, thus keeping the dump from ending cleanly. Right now I am looking at the st_mode flag, which changes when the tty is in use, but I hope there is a more elegant solution.
