Re: how to use angle operator with timeout?

The basic technique just involves the alarm function...

use 5.010;
use strict;
use warnings;
use Try::Tiny;

my $line;

try {
    local $SIG{ALRM} = sub { die "ALARM\n" };
    alarm 10;
    say "Please enter some text, but quick!";
    $line = <>;
    chomp $line;
    alarm 0;
}
catch {
    my $e = shift;
    $e =~ /^ALARM/ ? warn("timeout\n") : die($e);
};

say "Got: '$line'";

Does that work on *nix? Cos it never times out on Windows. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

http://perldoc.perl.org/perlport.html#alarm Emulated using timers that must be explicitly polled whenever Perl wants to dispatch "safe signals" and therefore cannot interrupt blocking system calls. (Win32)	[reply]

I know that they do not work on win32, and why. My question was: can signals -- alarm generated or otherwise -- interrupt blocking IO on *nix in under the auspices of safe-signals?

"Does that work on nix? Cos it never times out on Windows."* Works for me (on Linux). `package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name`	[reply]
