namespace std::this_thread {
  thread::id get_id() noexcept;

  void yield() noexcept;
  template<class Clock, class Duration>

thread::id this_thread::get_id() noexcept;
Returns: An object of type thread​::​id that uniquely identifies the current thread of execution.
No other thread of execution shall have this id and this thread of execution shall always have this id.
The object returned shall not compare equal to a default constructed thread​::​id.
void this_thread::yield() noexcept;
Effects: Offers the implementation the opportunity to reschedule.
Synchronization: None.
template<class Clock, class Duration> void sleep_until(const chrono::time_point<Clock, Duration>& abs_time);
Effects: Blocks the calling thread for the absolute timeout ([thread.req.timing]) specified by abs_­time.
Synchronization: None.
Throws: Timeout-related exceptions ([thread.req.timing]).
template<class Rep, class Period> void sleep_for(const chrono::duration<Rep, Period>& rel_time);
Effects: Blocks the calling thread for the relative timeout ([thread.req.timing]) specified by rel_­time.
Synchronization: None.
Throws: Timeout-related exceptions ([thread.req.timing]).
