# Parallel::ForkManager::Child(3pm)

role adopted by forked Parallel::ForkManager processes

## NAME

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

## VERSION

version 2.04

## 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.
