NAME

IO::Async::SignalProxy - a class to allow handling of POSIX signals with IO::Async-based IO

SYNOPSIS

use IO::Async::SignalProxy;

my $sigproxy = IO::Async::SignalProxy->new(
   signal_HUP => sub { reread_config() },
);

my $set = IO::Async::Set::...
$set->add( $sigproxy );

DESCRIPTION

This module provides a class that allows POSIX signals to be handled safely alongside other IO operations on filehandles in an IO::Async::Set. Because signals could arrive at any time, care must be taken that they do not interrupt the normal flow of the program, and are handled at the same time as other events in the IO::Async::Set's results.

CONSTRUCTOR

$proxy = IO::Async::SignalProxy->new( %params )

This function returns a new instance of a IO::Async::SignalProxy object. The %params hash takes keys that specify callback functions to run when signals arrive. They are all of the form

signal_$NAME => sub { ... }

where $NAME is the basic POSIX name for the signal, such as TERM or CHLD.
