Shared_ptr overloads of atomic functions
Webb10 mars 2024 · The std::atomic_ref class template applies atomic operations to the object it references. For the lifetime of the std::atomic_ref object, the object it references is considered an atomic object. If one thread writes to an atomic object while another thread reads from it, the behavior is well-defined (see memory model for details on data races). WebbClass-specific overloads. Both single-object and array allocation functions may be defined as public static member functions of a class (versions ()).If defined, these allocation functions are called by new-expressions to allocate memory for single objects and arrays of this class, unless the new expression used the form :: new which bypasses class …
