NAME
    Child::Socket - Child with socket support.

DESCRIPTION
    Lets you create a Child object, disconnect from it, and reconnect later
    in the same or different process.

REQUIREMENT NOTE
    Requires UNIX socket support.

SYNOPSIS
  BASIC
        use Child::Socket;

        # Build with IPC
        my $child = Child::Socket->new(sub {
            my $self = shift;
            $self->say("message1");
            my $reply = $self->read();
        }, socket => 1 );

        my $message1 = $child1->read();
        $child->say("reply");

CONSTRUCTOR
    $class->new( sub { ... } )
    $class->new( sub { ... }, pipe => 1 )
    $class->new( sub { ... }, socket => 1 )
    $class->new( sub { ... }, socket => $file )
        Create a new Child object. Does not start the child.

    $class->existing( $socket_filename )
        Create a new instance that connects to an existing child.

OBJECT METHODS
    Inherits everything from Child.

    $child->connect( $timeout )
        In parent process this will attempt to connect to the child unless
        already connected. Throws an exception if the socket file does not
        exist after the timeout expires. Once connected, the child PID will
        be returned.

        In the child process this will accept an incomming connection. This
        will return undef if no incomming connection occurs before the
        timeout expires.

        NOTE: Only one connection can be maintained at a time. Will return
        undef if already connected.

    $child->disconnect()
        Disconnects if connected.

    $child->socket_file()
        Get the socket file name.

    $child->is_socket()
        Check if this is a socket connection.

    $child->is_pipe()
        Check if this is a pipe connection.
