No, one more bug in there: Eric did
+ case TIOCGPTPEER:
+ retval = ptm_open_peer(file, tty, (int)arg);
+ break;
to call that ptm_open_peer(), but that's bogus. The "break;" will just
cause it to continue with the tty ioctl handling, and result in
-ENOTTY in the end.
So it actually *did* open the slave, but then threw the returned fd value away.
It should just do a "return ptm_open_peer(file, tty, (int)arg);" instead.
