load函数用于获取原子变量的当前值。它有以下两种形式: T load(memory_order order = memory_order_seq_cst) const noexcept; operator T() const noexcept; 其中,第一种形式是显式调用load函数,第二种形式是通过重载类型转换运算符实现隐式调用。 load函数的参数memory_order表示内存序,也就是对原子变量的读操...
It is deprecated if std::atomic<T>::is_always_lock_free is false and any volatile overload participates in overload resolution. (since C++20)Return valueoperator++() and operator--() return the value of the atomic variable after the modification. Formally, the result of incrementing/...
一、背景介绍： 函数指针始终不太灵活，它只能指向全局或静态函数，对于类成员函数、lambda表达式或其他可...
