A biblioteca atômica fornece componentes para refinadas operações atômicas que permitem programação concorrente lockless. Cada operação atômica é indivisível em relação a qualquer outra operação atômica que envolve o mesmo objeto. Objetos atômicos são os únicos objetos C + + livres de raças de dados, isto é, se uma thread escreve para um atômica enquanto outro segmento lê-lo, o comportamento é bem definido.

Original:

The atomic library provides components for fine-grained atomic operations allowing for lockless concurrent programming. Each atomic operation is indivisible with regards to any other atomic operation that involves the same object. Atomic objects are the only C++ objects free of data races; that is, if one thread writes to an atomic while another thread reads from it, the behavior is well-defined.
