Parallel::ForkManager::Child(3pm) User Contributed Perl Documentation Parallel::ForkManager::Child(3pm)

NAME

Parallel::ForkManager::Child - role adopted by forked Parallel::ForkManager processes

VERSION

version 2.02

SYNOPSIS

   use 5.10.0;
   use Parallel::ForkManager;
   my $fm = Parallel::ForkManager->new;
   say "parent does not consume the child role: ", $fm->does('Parallel::ForkManager::Child');
   $fm->start_child(sub{ 
        sleep $_;
        say "but the child does: ", $fm->does('Parallel::ForkManager::Child');
        say "child $_ says hi!"
   }) for 1..3;

DESCRIPTION

When the parent Parallel::ForkManager object forks a child process, its forked incarnation consumes this role. The role doesn't do much: it changes the returning values of "is_child" and "is_parent" in the way you'd expect, change "start" so that it'd die if called from within the child, and change the implementation of "finish" to potentially send data back to the parent process.
