Hello,
My name is Marcelo and I am a student in computer science facing a
project that is getting difficult to implement.
In order to solve some of my problems I would like to get some information.
I would like to know if it is possible in Linux to know from user space
which is the last active tty attached to an user i choose(the last tty
which had some activity in it). I will be root or some other user which
will have the proper privileges. I am willing to do any combination of
system calls and tricks.
If it is not possible to do from user space then I would like to do it
myself inside the kernel. I need to know where should I start reading to
have the knowledge required to do the changes in the kernel (in my local
copy of course).
I have some knowledge of the kernel and some little experience in
programming inside the kernel (mainly i played with the scheduler and
the virtual memory).
Thank you in advance,
Marcelo Taube
