std::atomic_notify_all(3) C++ Standard Libary std::atomic_notify_all(3) NAME std::atomic_notify_all - std::atomic_notify_all Synopsis Defined in header <atomic> template< class T > (1) (since C++20) void atomic_notify_all( std::atomic<T>* object ); template< class T > (2) (since C++20) void atomic_notify_all( volatile std::atomic<T>* object ); Performs atomic notifying operations. Unblocks all threads blocked in atomic waiting operations (i.e. std::atomic_wait(), std::atomic_wait_explicit(), or std::atomic::wait()) on *object, if there are any; otherwise does nothing. Equivalent to object->notify_all(). Parameters object - pointer to the atomic object to notify Return value (none) Notes This form of change-detection is often more efficient than simple polling or pure spinlocks. Example This section is incomplete Reason: no example See also notify_one notifies at least one thread waiting on the atomic object (C++20) (public member function of std::atomic<T>) notify_all notifies all threads blocked waiting on the atomic object (C++20) (public member function of std::atomic<T>) atomic_wait atomic_wait_explicit blocks the thread until notified and the atomic value changes (C++20) (function template) (C++20) atomic_notify_one notifies a thread blocked in atomic_wait (C++20) (function template) Category: * Todo no example http://cppreference.com 2024.06.10 std::atomic_notify_all(3)
