std::pointer_traits

成员函数

pointer_traits::pointer_to (C++11)

pointer_traits::to_address (C++20)(可选)

 

定义于头文件 <memory>
static element_type* to_address(pointer p) noexcept;		(C++20 起) (程序定义特化的可选成员)

构造裸指针，结果引用的对象与其仿指针（“缀饰指针”）参数相同。

若定义此函数，则它是 pointer_to 的反函数，它作为定制点存在并为 std::to_address 所调用。

参数

p

-

缀饰值指针/仿指针对象

返回值

element_type* 类型的裸指针，其所引用的内存位置与参数 p 相同。
