std::atomic Extensions
Understand how C++20 extends std atomic capabilities by supporting floating-point types and enabling thread synchronization with notify and wait functions. Learn about atomic shared pointers and the practical differences between condition variables, promises, futures, and atomic flags to write safer concurrent code.
We'll cover the following...
In C++20, like std::atomic_ref, std::atomic can be instantiated with floating-point types such as float, double, and long double. In addition, std::atomic_flag and std::atomic can be used for thread synchronization via the member functions notify_one, notify_all, and wait. Notifying and waiting is available on all partial and full specializations of std::atomic (bools, integrals, floats and pointers) and std::atomic_ref.
