NAME
PerlIO::via::Timeout - a PerlIO layer that adds read & write timeout to a handle
VERSION
version 0.14
SYNOPSIS
use PerlIO::via::Timeout qw(timeout_strategy);
open my $fh, '<:via(Timeout)', 'foo.html';
# creates a new timeout strategy with 0.5 second timeout, using select as
# timeout system
timeout_strategy($fh, 'Select', read_timeout => 0.5);
my $line = <$fh>;
if ($line == undef && $! eq 'Operation timed out') { ... }DESCRIPTION
This package implements a PerlIO layer, that adds read / write timeout. This can be useful to avoid blocking while accessing a filehandle, and fail after some time.
FUNCTIONS
timeout_strategy
# creates a L<PerlIO::via::Timeout::Strategy::Select strategy> with 0.5
# read_timeout and set it to $fh
timeout_strategy($fh, 'Select', read_timeout => 0.5);
# same but give an alarm strategy instance directly
my $strategy = PerlIO::via::Timeout::Strategy::Alarm->new(write_timeout => 2)
timeout_strategy($fh, $strategy);
# used as a getter, returns the current strategy
my $strategy = timeout_strategy($fh);AVAILABLE STRATEGIES
