Hello, I'm having a trouble programming a special login shell, and would like to hear any opinions on this. I want this shell (which automatically becomes a session leader) to release its ctty but remain unterminated (the ctty must be taken by its child). However, there seems to be no easy way to do this; termios(4) says one must call setsid() to release its ctty, but setsid(2) says the call will fail if the caller is already a session leader. Would there be any other way for a session leader to release its ctty without terminating itself? TIA. Cheers, Eugene Kim PS. I'm now using a workaround that the shell will forward the SIGHUP that it received because it's a session leader, but this isn't a clean way. :-p -- Eugene M.
