Thanks Dave. The thing is that the child processes get forked with a fork() invocation. What's more not only the child pids are invisible to cygwin, but also their parent is invisible. That is why I'm wondering isn't there a way to make them part of the processes that are visible by cygwin. My purpose is - to be able to kill them with kill() and to use the signal system.
