Of course, one doesn't need those newfangled thread thingies. Here's one that can easily be backported to old versions of perl, and is using fork() and signals.

#!/usr/bin/perl -w my $hp = 100; my $pid; sub get_hit; sub get_hit { unless (-- $hp) { kill USR2 => $pid or warn "Failed to send victory: $!\n"; print "$$: Arrrgh, I am dying!\n"; exit; } print "$$: I got hit! $hp hitpoints left.\n"; $SIG {USR1} = \&get_hit; } $SIG {USR1} = \&get_hit; $SIG {USR2} = sub {print "$$: I won! I won!\n"; exit}; $pid = fork; die "Fork failed\n" unless defined $pid; $pid ||= getppid; while (1) { my $timeleft = rand 1; (undef, $timeleft) = select (undef, undef, undef, $timeleft) while $timeleft; kill USR1 => $pid; # Ignore errors. } __END__

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
