std::pointer_traits

成员函数

pointer_traits::pointer_to (C++11)

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

 

定义在头文件 <memory> 中
static element_type* to_address( pointer p ) noexcept;		(自 C++20 起) (程序定义的专门化的可选成员)

构造一个原始指针，该指针引用与其指针式 ("奇特指针") 参数相同的对象。

如果定义了此函数，则它是 pointer_to 的反函数，并且存在作为 std::to_address 所调用的定制点。

参数

p

-

奇特指针/指针式对象

返回值

类型为 element_type* 的原始指针，该指针引用与参数 p 相同的内存位置。
