[Boost-users] [chrono][thread] Best way to wait?

Hi, can someone clarify: 1. what is the difference between: const auto wait_time = boost::chrono::miliseconds( 8 ); boost::mutex mutex; boost::unique_lockboost::mutex lock( mutex ); boost::condition_variable wait_condition; wait_condition.wait_for( lock, wait_time ); and const auto wait_time = boost::chrono::miliseconds( 8 ); boost::this_thread::sleep_for( wait_time ); 2. are there other ways to wait? (I mean make the thread sleep, not looping until it's time) Joel Lamotte
