in reply to Simple way to find on Windows, whether a process is running

From the perlport manpage you referenced:

As in Unix, if $sig is 0 and the specified process exists, it returns true without actually terminating it. (Win32)

And from experience, kill 0, $pid works fine. It doesn't do it using signals, but the emulation is good.

    At least on Windows 7, this is not true anymore. I tried it with various PIDS - no matter, whether the process exists or not, kill always returned true :-( However, this is Perl 5.8.8. This Perl was implemented before Windows 7, so it could be that a newer Perl version has a better "kill".

      From the Active State change log:

      Bug Fixes and Changes since build 821

      ...

      kill(0, $pid) was always returning TRUE in build 820 on Windows. It now returning the correct values again (bug 67519).

      Upgrade. Works okay on AS 5.8.9:

      c:\test>\perl32\bin\perl -le"print $]; print kill 0, $_ for 3844, 4844

        I'm not sure whether I'll get permission to upgrade (and in this case, I would go straight to 5.12 anyway).

        Any suggestions how to solve it within 5.8.8?
