静态函数和变量用C [英] Static functions and variables in C

问题描述

我知道什么是使用面向对象语言的静态变量，不过，我不明白什么是C.使用静态关键字的含义的目的
有人可以解释给我吗？

I know what is the purpose of using static variables in an object oriented language, still, I don't understand what is the meaning of using the "static" keyword in C. Can someone explain it to me?

推荐答案

在函数或全局变量，静态使得函数或全局变量本地到该文件;其他文件无法通过该名称访问该功能或全局变量（但如果你给一个指向它拿走他们可以访问它）。

On a function or global variable, static makes the function or global variable local to that file; other files cannot access that function or global variable by that name (but they can access it if you give a pointer to it away).

在一个局部变量，它使充当如果它是一个全局变量，但仅仅是函数内部访问（除非再次，你给它的指针距离）。

On a local variable, it makes it act as if it was a global variable, but is only accessible within that function (unless, again, you give a pointer to it away).
