Although I have been a Unix front-end user for three years now,
it is my first time to interact directly with Unix from my
programs!!.

A login operation, I do think, is handled by some daemon or an
init forked process. (Am I right ?)
Now, is there anyway, ie. writting a shell script, a program,
etc... in such a way that the login daemon notifies a process
of mine that a person has logged in ?

My current solution to this problem, which I don't like,
is running a process that constantly reads the /etc/utmp
file and checks for user processes (ie. a user logged in!).
Can anybody help please ?!
Please e-mail any answers!!.

Thanks very much.
