       POE::Pipe::OneWay - a portable API for one-way pipes


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


       The right way to create an anonymous pipe varies from one operating system to the next.
       Some operating systems support "pipe()".  Others require "socketpair()".  And a few
       operating systems support neither, so a plain old socket must be created.

       POE::Pipe::OneWay will attempt to create a unidirectional pipe using "pipe()",
       "socketpair()", and IO::Socket::INET, in that order.  Exceptions are hardcoded for
       operating systems with broken or nonstandard behaviors.

       The upshot of all this is that an application can portably create a one-way pipe by
       instantiating POE::Pipe::OneWay.  The work of deciding how to create the pipe and opening
       the handles will be taken care of internally.

       POE::Pipe::OneWay may be used outside of POE, as it doesn't use POE internally.


   new [TYPE]
       Create a new one-way pipe, optionally constraining it to a particular TYPE of pipe.  One-
       way pipes have two ends: a "read" end and a "write" end.  On success, new() returns two
       handles: one for the "read" end and one for the "write" end.  Returns nothing on failure,
       and sets $!  to explain why the constructor failed.

         my ($read, $write) = POE::Pipe::OneWay->new();
         die $! unless defined $read;

       TYPE may be one of "pipe", "socketpair", or "inet".  When set, POE::Pipe::OneWay will
       constrain its search to either "pipe()", a UNIX-domain "socketpair()", or plain old
       sockets, respectively.  Otherwise new() will try each method in order, or a particular
       method predetermined to be the best one for the current operating environment.


       POE::Pipe::OneWay may block up to one second on some systems if failure occurs while
       trying to create "inet" sockets.
