NAME

IOMux::File::Read - write to file

INHERITANCE

IOMux::File::Read
  is an IOMux::Handler::Read
  is an IOMux::Handler

SYNOPSIS

my $mux = IOMux::Select->new;  # or ::Poll

use IOMux::Open '<';
my $file = $mux->open('<', $filename);

use IOMux::File::Read;
my $file = IOMux::File::Read->new(file => $filename);
$mux->add($file);

$file->getline(sub {print "\n"});

DESCRIPTION

In an event driven program, reading is harder to use than writing: the read will very probably be stalled until data has arrived, so you will need a callback to handle the resulting data.
