Re: killing off a process tree



I would like this to be portable on both linux and windows. Seemingly
you can only use 0-9 on windows, and none of them seems to kill a tree.

Some of them are even undefined signals. Can you do this process-group

leader thing on windows? Also , I would like to clarify my original
question. I meant taht I would call a parent process to open, which is

some program. And that program can POTENTIALLY open up other children
processes. The thing is I only have the pid of the parent, and when I
kill the parent, only the parent will die. Is there a way that I can
kill the parent and the children that it sprang (which I did not
provide
the exec code for since they were provided by the parent itself that I
did not code).

It seems that Process.kill(9, pid) only kills the parent and not the
children.

You are killing process, so you will have "zombies" left sometimes.
Try sig 15 instead of using 9. Try sigquit (3) as well...
