Need Help??

in reply to Many children, but never more than a fixed number at once.

I find Parallel::ForkManager good for this kind of thing as it lets you write:

use Parallel::ForkManager;
$pm = new Parallel::ForkManager($MAX_PROCESSES);
foreach $data (@all_data) {
    # Forks and returns the pid for the child:
    my $pid = $pm->start and next; 

    ... do some work with $data in the child process ...

    $pm->finish; # Terminates the child process
}

Yeah, but that requires you to do three lines of code - to create an object (why? What's so OO about this?), and two calls (to `->start` and `->finish`) for each piece of code you want to execute. With `mfork` or `afork`, all you have is one call. But this is Perl, so there are more ways to do things. Abigail	[reply] [d/l] [select]
