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 }
