Атомарно заменяет значение указано на
obj с результатом побитового XOR между старым значением obj и arg, и возвращает значение obj состоялось ранее. Операция чтения-модификации-записи. Первая версия заказы доступ к памяти по memory_order_seq_cst, вторая версия заказы доступ к памяти по order.Original:
Atomically replaces the value pointed by
obj with the result of bitwise XOR between the old value of obj and arg, and returns the value obj held previously. The operation is read-modify-write operation. The first version orders memory accesses according to memory_order_seq_cst, the second version orders memory accesses according to order.The text has been machine-translated via Google Translate.

Это общие функции определены для всех типов атомного объекта.
A это тип атомного объекта, M либо неатомической типа, соответствующие A если A является атомная целого типа, или ptrdiff_t если A является атомарный тип указателя.Original:
This is a общие функции defined for all atomic object types.
A is the type of an atomic object, M is either the non-atomic type corresponding to A if A is atomic integer type, or ptrdiff_t if A is atomic pointer type.The text has been machine-translated via Google Translate.
