namespace std::this_thread { thread::id get_id() noexcept; void yield() noexcept; template<class Clock, class Duration> void sleep_until(const chrono::time_point<Clock, Duration>& abs_time); template<class Rep, class Period> void sleep_for(const chrono::duration<Rep, Period>& rel_time); }

thread::id this_thread::get_id() noexcept;
1
#
Returns: An object of type thread​::​id that uniquely identifies the current thread of execution.
Every invocation from this thread of execution returns the same value.
The object returned does not compare equal to a default-constructed thread​::​id.
🔗
void this_thread::yield() noexcept;
2
#
Effects: Offers the implementation the opportunity to reschedule.
3
#
Synchronization: None.
🔗
template<class Clock, class Duration> void sleep_until(const chrono::time_point<Clock, Duration>& abs_time);
4
#
Effects: Blocks the calling thread for the absolute timeout ([thread.req.timing]) specified by abs_time.
5
#
Synchronization: None.
6
#
Throws: Timeout-related exceptions ([thread.req.timing]).
🔗
template<class Rep, class Period> void sleep_for(const chrono::duration<Rep, Period>& rel_time);
7
#
Effects: Blocks the calling thread for the relative timeout ([thread.req.timing]) specified by rel_time.
8
#
Synchronization: None.
9

Throws: Timeout-related exceptions ([thread.req.timing]).
