Could you explain what you mean by " I am looking for a way to get the tty
controlling
a certain process". This seems backwards to me or am I misinterpreting what
you said?
I haven't seen anything that shows ttys pointing to a process. It may
exist, but I don't
know where you would find it if it does. I just know that processes attach
tty devices
via file descriptors on Linux and Unix systems. The read command, in
several shells,
supports this with the "-u N" option. Maybe I'm just looking at this from
the wrong
perspective(wouldn't  be the first time).

Regards,

Jim
