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

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?

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.)

static tells that a function or data element is only known within the scope of the compilation unit, so the answer to your question is Yes you will be able to declare a static function with the same name and even with the same signature in two different compilation unit.

Yes, this is OK and one of the points of the static keyword.
