NAME

POE::Pipe::OneWay - portable one-way pipe creation (works without POE)

SYNOPSIS

  my ($read, $write) = POE::Pipe::OneWay->new();
  die "couldn't create a pipe: $!" unless defined $read;

DESCRIPTION

POE::Pipe::OneWay makes unbuffered one-way pipes or it dies trying.

Pipes are troublesome beasts because the different pipe creation methods have spotty support from one system to another. Some systems have pipe(), others have socketfactory(), and still others have neither.

POE::Pipe::OneWay tries different ways to make a pipe in the hope that one of them will succeed on any given platform. It tries them in pipe() -> socketpair() -> IO::Socket::INET order.

So anyway, the syntax is pretty easy:

  my ($read, $write) = POE::Pipe::OneWay->new();
  die "couldn't create a pipe: $!" unless defined $read;

And now you have a pipe with a read side and a write side.

DEBUGGING

It's possible to force POE::Pipe::OneWay to use one of its underlying pipe methods. This was implemented for exercising each method in tests, but it's possibly useful for others.

However, forcing OneWay's pipe method isn't documented because it's cheezy and likely to change. Use it at your own risk.

BUGS

The INET domain socket method may block for up to 1s if it fails.
