Hi,
My query is...

I have a parent process which forks a child process to perform certain
task.
I wish to terminate the child process after certain amount of time
(say 60 secs).
Since I dont wish to leave any zombie process, I need to notify the
Child that it has to terminate now.
The parent can terminate only after all the child processes have
terminated.

How can I achieve this task.
I heard something about SIGUSR1 signal but not sure how to use it and
how it can be useful...

Can anyone guide me please?

Thanks.

you are off-topic for comp.lang.c. Please post to a platform specific
ng. For instance if you are on a Unix system try comp.unix.programming

Remember the child's PID when you fork(2), and send it a suitable
signal with kill(2). Then in the parent process, call wait(2) so that
the child doesn't remain in the kernel process table as a zombie.
