std::shared_ptr 是一种通过指针保持对象共享所有权的智能指针。多个 shared_ptr 对象可持有同一对象。下列情况之一出现时销毁对象并解分配其内存: 最后剩下的持有对象的 shared_ptr 被销毁; 最后剩下的持有对象的 shared_ptr 被通过 operator= 或reset() 赋值为另一指针。 用delete 表达式或在构造期间提供给 sha

Those non-member functions may be additionally overloaded for types that are not specializations of std::atomic, but are able to guarantee atomicity. The only such type in the standard library is std::shared_ptr<T>. The text has been machine-translated via Google Translate. You can help to...
