Timer(3pm)
NAME
Coro::Timer - timers and timeouts, independent of any event loop
SYNOPSIS
use Coro::Timer qw(sleep timeout); # nothing exported by default sleep 10;
DESCRIPTION
This package implements a simple timer callback system which works
independent of the event loop mechanism used.
- $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 nothing happens. This is used 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} - sleep $seconds
This function works like the built-in sleep, except maybe more
precise and, most important, without blocking other coroutines.
