Coro::Timer(3pm)

timers and timeouts, independent of any event loop

NAME

Coro::Timer - timers and timeouts, independent of any event loop

SYNOPSIS

 # This package is mostly obsoleted by Coro::AnyEvent.
 use Coro::Timer qw(timeout);
 # nothing exported by default

DESCRIPTION

This package has been mostly obsoleted by Coro::AnyEvent, the only really useful function left in here is "timeout".

$flag = timeout $seconds

This function will wake up the current coroutine after $seconds seconds and sets $flag to true (it is false initially). If $flag goes out of scope earlier then nothing happens.

This is used by Coro itself to implement the "timed_down", "timed_wait" etc. primitives. It is used like this:

   sub timed_wait {
      my $timeout = Coro::Timer::timeout 60;
      while (condition false) {
         Coro::schedule; # wait until woken up or timeout
         return 0 if $timeout; # timed out
      }
      return 1; # condition satisfied
   }
