函数指针和函数指针之间的区别 [英] Difference between function pointers and pointer to function

问题描述

大家好，



你能解释一下功能指针与功能指针之间的区别吗？



据我所知，函数指针是一个存储函数地址的指针变量，但指向函数的指针 n是一个以函数指针作为参数的函数。 />




如果我错了，请纠正我。





问候，

Hello Everyone,

can you please explain the difference between function pointers and pointer to function?

As I understand function pointer is a pointer variable that stores address of a function however pointer to a function is a function which takes function pointer as an argument.


Correct me if i am wrong.


Regards,
Joy

推荐答案

它们是同义词 - 函数指针和指向函数的指针描述一个可以保存函数地址的对象。

They're synonymous - "a function pointer" and "a pointer to a function" describe an object that can hold the address of a function.

完全没有。两者都是相同的：两者都是指针，但强打字是避免问题的关键。



在Windows上经常与 GetProcAdress 和LoadLibrary。



采用指针的函数是正常函数。例如：大多数字符串函数都使用指向char数组（也就是字符串）的指针。

Not at all. It is both the same: both are pointers, but strong typing is key to avoid problems.

On Windows often used with GetProcAdress and LoadLibrary.

A function which takes a pointer is a normal function. For example: the most string functions are working with pointers to char arrays (aka strings).
