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
}
