Parallel::ForkManager::Child - role adopted by forked Parallel::ForkManager processes
version 2.02
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 the Parallel::ForkManager manpage 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.
