A Simple Key For sleep Unveiled
The returned price of overload (3) signifies whether pred evaluated to real, irrespective of whether there was a quit asked for or not.

These elements are supplied for fine-grained atomic functions letting for lockless concurrent programming. Each atomic Procedure is indivisible with regards to any other atomic Procedure that entails a similar object. Atomic objects are no cost of information races.
Offers a hint to your implementation to reschedule the execution of threads, allowing other threads to run.
The mutex class is actually a synchronization primitive that could be applied to shield shared data from becoming concurrently accessed by a number of threads.
blocks The present thread until finally the issue variable is awakened or until eventually specified time place has long been arrived at (public member function) [edit] Native deal with
A clock consists of a place to begin (or epoch) plus a tick price. For example, a clock could possibly have an epoch of January 1, 1970 and tick each next. C++ defines many clock kinds: Described in header Outlined in namespace std::chrono
In any circumstance, the purpose also could wait for extended than right up until following abs_time has long been achieved because of scheduling or useful resource competition delays.
The implementation may perhaps lengthen the actions of the primary overload of std::async by enabling additional (implementation-outlined) bits within the default start policy.
No two std::thread objects may possibly represent the exact same thread of execution; std::thread isn't CopyConstructible or CopyAssignable, even though it is MoveConstructible and MoveAssignable.
The standard suggests that a gentle clock is accustomed to evaluate the duration. If an implementation employs a system clock alternatively, the hold out time can also be delicate to clock adjustments.
A calling thread owns a mutex from your time that it properly calls both lock or try_lock until eventually it calls unlock.

The result or exception is positioned while in the shared condition connected to the returned std::long term and only then it really is created All set. All even more accesses Stages of sleep to the exact same std::upcoming will return The end result straight away.
