Can we use same function name in 2 different file in C by giving static?

Question

Can we use same function name in 2 different file in C by giving static? Like static myfunc() in file1.c and static myfunc() in file2.c. Will linker understand the scope or it will throw the error?

Answer 1

static 告诉函数或数据元素只在编译单元的范围内是已知的 ， 所以你的问题的答案是肯定的，你将能够声明一个具有相同名称的静态函数， 甚至在两个不同的编译中使用相同的签名单位 。

Answer 2

是的，这是可以的，并且是static关键字的一个要点。

Answer 3

Global names declared static have internal linkage , which means that such a name is private to the translation unit. More specifically, within one translation unit, all static declarations of a name refer to the same object or function, but in each translation unit, such a declaration refers to a distinct object or function. (By contrast, all names with external linkage refer to the same entity across the entire program.)
