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
              }
