win32utils devel - Oct 2011 - Interesting use of Process.kill in win32-process

Hi all,

I stumbled onto this article today:
http://blog.robseaman.com/2008/12/12/sending-ctrl-c-to-a-subprocess-with-ruby

It''s actually a few years old but I hadn''t seen it before.
He''s using
an undocumented feature where passing nil as the pid has the effect of
passing a null to the dwProcessGroupId argument of the
GenerateConsoleCtrlEvent function. If this parameter is zero, the
signal is generated in all processes that share the console of the
calling process.

Anyway, I thought it was interesting. I''m wondering if I should
document that as "official" behavior, mainly to prevent us from
accidentally breaking it if people are relying on it.

Regards,

Dan
