Hi,

In my understanding, we should introduce SIGPIPE signal to kill a parent process when its pipe is broken.
It might be a proper solution to achieve what you want if we set its default behavior as terminating a process.

It might be preferable to implement a signal handling mechanism ( #11 ) beforehand.

Thanks,
