Re: how to get the output from: Win32::Process::Create

You apparently have two requirements. One is that you need to capture
the output of the program. The other is that you need to get the pid

to me, to be contraditory.

I guess the other possibility is to fork your program, and set up the
child to have a signal handler to be notified when the parent wants to
kill it....

[untested]

my $pid = fork();
if ($pid == 0) { #child

$SIG{INT} = sub { print "Parent told me to die!\n"; exit };

open my $pipe, "test.exe |" or die "Cannot open pipe: $!";
while (my $line = <$pipe>) {
process_line($line);
}
print "test.exe ended before parent told me to die!\n";
}
else { #parent
#do stuff
# la la la
if (want_to_kill()) {
kill ('INT', $pid);
}
#do more stuff, la la la
}
