=head1 NAME

AnyEvent::Capture - Call asynchronous APIs synchronously

=head1 VERSION

version 0.1.1

=head1 SYNOPSIS

    use AnyEvent::Capture;
    use AnyEvent::Socket qw( inet_aton );
    
    # Call the async version of inet_aton in a synchronous fashion, but
    # while we're doing this other events will fire.
    my @ips = capture { inet_aton( 'localhost', shift ) };

    # An example of waiting for a child without blocking events from firing
    # while we wait.
    sub wait_for_child($) {    
        my( $pid ) = @_;
        my($rpid,$rstatus) = capture { AnyEvent->child(pid=>$pid, cb=>shift) };
        return $rstatus;
    }

=head1 HELPERS

=head2 sub capture( CodeRef $todo ) returns Any

Executes $todo, passing it a CodeRef to be used as an event listener.  After
$todo returns, it enters the event loop and waits till the CodeRef is
called.  The return value of $todo will be stored until such time as the
CodeRef is called.  It then returns the arguments that were passed to the
CodeRef.

In so doing, it allows you to call an asychronous function in a synchronous
fashion.

This module is similar to L<Data::Monad::CondVar> but much simpler.  You
could write the example using L<Data::Monad::CondVar> this way:

    my @ips = (as_cv {inet_aton( 'localhost', shift ) })->recv;
