Hi!
Alternatively, you can avoid the need to explicitly use a while loop by calling the overloaded version of timed_wait() that takes a predicate argument. This version does the loop for you internally. E.g.:
if (!(m_condition.timed_wait (lock, time, boost::bind<int> (boost::mem_fn (&AsyncQueue::m_counter), this)))) return;
Thank you! I saw overloaded version of timed_wait() but didn't understand its purpose.
On a separate point, there is a bug in your usage of the xtime struct in main():
xtime_get(&time, TIME_UTC); time.nsec += 10000; queue.timed_pop(time);
You cannot simply add a value to time.nsec and then use the struct, because nsec is required to be in the range [0,999999999]. In really code I use sec, not nsec. But you are rigth.
