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