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 );
A thread waiting on a condition variable (a) can be explicitly notified and (b) may wake up before the time has expired (spurious wakeups). If you just want to sleep for a fixed amount of time, then sleep_for is the right tool.
2. are there other ways to wait? (I mean make the thread sleep, not looping until it's time)
