WebOne full specialization for the type bool and its typedef name is defined that is treated as a non-specialized std::atomic except that it has standard layout, trivial default constructor, trivial destructors, and supports aggregate initialization syntax: 2)Full specializations and typedefs for integral types, as follows: WebAtomic types are types that encapsulate a value whose access is guaranteed to not cause data races and can be used to synchronize memory accesses among different threads. This header declares two C++ classes, atomic and atomic_flag, that implement all the features of atomic types in self-contained classes.
