poe::pipe::oneway
POE::Pipe::OneWay(3pm) User Contributed Perl Documentation POE::Pipe::OneWay(3pm)
NAME
POE::Pipe::OneWay - a portable API for one-way pipes
SYNOPSIS
my ($read, $write) = POE::Pipe::OneWay->new();
die "couldn't create a pipe: $!" unless defined $read;
DESCRIPTION
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.
PUBLIC METHODS
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.
BUGS
POE::Pipe::OneWay may block up to one second on some systems if failure occurs while trying to create "inet" sockets.
