in thread Killing on Windows

Thanks for the explanation. I now see that my real problem is that the kill of course kill only the process directly invoked; but that process had at this time already invoked other child processes, and *they* are of course not killed, and they run to the end.

What possibilities exist in Windows to kill a process *including* all of its children in one go? On Solaris, I would use pkill. I think this is such a common problem that there is likely also something available for Windows...

    See Win32::Job.

      Yes, this is a possibility indeed. I just was curious whether there is a possibility to kill jobs started with system(1,...); sorry if I was not clear enough in this respect.

      It turns out that at least with my tests, I did find a solution which seems to work: Using a negative kill signal (kill -9) killed also my children. Knowing that Windows gets funny at times, I wonder whether this is indeed a reliable solution, or whether there could be cases when this strategy fails to work.

        Hm. Which version of Perl are you using?

        Update: I'm not sure when it was added, but the latest sources show that any negative signal value is now taken to mean "kill this process tree with prejuduce".
