A more Unix-y way to do this would be to use the alarm function. See 'perldoc -f alarm' for details.
#!/usr/bin/perl use strict; my $interval = 60; # seconds between calls + # sub will be called every $interval seconds my $process = sub { print "processing!\n" }; + # engage the alarm system $SIG{ALRM} = sub { &$process; alarm $interval; }; + alarm $interval; + # function will be called every 60 seconds for rest of program...

Another alternative would be to upgrade the program to use POE events. This would be the route I would take. The alarm demo is more for historical interest and fiddling than for anything else.

Use:  <p> text here (a paragraph) </p>

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
