He meant the perl function kill. it should work on Win32 as well.
Note that Perl 5.6 will always send a 'KILL' signal, i.e.
kill 9, $pid;
or
kill 'KILL', $pid;
regardless what signal you specify.
Perl 5.8 has some support for the 'INT' signal on Windows, but
unfortunately you cannot send 'INT' (Ctrl-C) to process groups but
only
single processes. Perl 5.8 started to always create new processes
as
process groups, so
kill 2, $pid;
or
kill 'INT', $pid;
will not work if the process has been created by Perl itself. The
process group creation is necessary because Perl often starts child
processes via cmd.exe. If it wouldn't mark them as a process
group, the
'KILL' signal would only terminate the cmd.exe process but not the
_real_ child process.
In Perl 5.8.1 it will be possible to send a 'BREAK' (Ctrl-Break)
signal
to other processes, and that one does indeed work with process
groups as
well. That will allow you to intercept the signal in the child process
and do your cleanup before terminating:
$SIG{BREAK} = sub {
# shut down
exit(1);
}
In summary:
* kill() in Perl 5.6.x on Windows maps all signals to 'KILL'.
* kill() in Perl 5.8.0 on Windows maps all signals except 'INT'
to 'KILL'.
* kill() in Perl 5.8.1 on Windows will map all signals except 'INT',
'BREAK' and 'TERM' to 'KILL'. It will also map 'TERM' to
'BREAK'.
Cheers,
-Jan

RE: Killing a process on a win32 box
Title: RE: Killing a process on a win32 box I dont believe that kill is native to XP. It does have a taskkill command built in though that you can either use the service name or PID for.
