I'm working on a script which forks a child process. I have done modifications for the parent to monitor the child. On maximum timeout I'm killing the child process. The issue is I'm running an exe from the child which doesn't die on kill the child. I tried to explicitly kill the process with taskkill on windows and it works fine. But I face portability issues because of using taskkill. Can anybody help on this?
overview:
$pid = fork;
# Fork error
if ( !defined($pid) ) {
print "ERROR: fork()\n";
exit;
} elsif ( $pid == 0 ) {
exec('C:\WINNT\system32\calc.exe');
exit;
} else {
# Parent process
# Monitors the child process for maximum timeout
# on timeout
kill 9,$pid;
exit;
}
On timeout I tried killing the child proces but the exe is still alive.I have two questions here:
1) Is there any way I can access the pid of the exe (called from the child process) from the parent process?
Reason: I tried Win32::Proc but the obj handle was not visible to the parent. I had the same issue while using pipes.
2) Is there a better way to monitor the child process?
Restriction: I'm forced to use only the standard modules and hence unable to download and use CPAN modules.
I'd appreciate any help on the issue.
