Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monk,

In my CGI script I am trying to fork another process for running some task in background (windows perl/activeperl)with fork() system call but found that in windows it's not supported. While searching found this node http://www.perlmonks.org/?node_id=104656 ... but in CPAN I don't find any Win32::CreateProcess module. Can I go for using Win32::Console Or it's only meant for console application.

.

Is there any other way I can fork a process for running in background. Please suggest.

Thanks.

    Hi Monks,

    After searching little more ... I used perl threading but the problem is it's waiting for the thread to complete if I join() else if I detach() then I dont get the returned data.

    Is there any way ... I can start the thread, come back to do some other thing and then wait for the thread to end and do something else and completes.

      It sounds like you want to poll your thread and not join it until it is joinable. Look into thread states, is_joinable() is probably what you seek.

        Hi,

        Thanks for the reply. I am facing a problem with threading. I am redirecting to a different page and then closing STDOUT, STDERR and calling the function in thread,detaching it...so that it kinda runs in background.

        But once I run the CGI script...nothing happens ... in process list I dont see any perl.exe process. perl process is exiting.

        Is it a bug? Or I am doing something wrong. Thanks
