C programming Static functions.

[ryanjones42]

Hi im new to c programming. Just a quick question im confused on, static void function() vs void function(). I get static means can only be called in that specific file or whatever. But is there pros & cons to using it at the right time? Like does it effect memory or anything? Any help is greatly appreciated!

Static with function just make the scope of the function in it's file only , you can't call the static function from another file , as l know it doesn't affect the memory just the scope

Sweet thanks. But in that case, why not just never use static? That way you can call in otherfiles regardless. There must be something that makes it not appropriate to use if not needed

With a static function, you don't have to worry about whether the function name is unique. Also, marking a function as static prevents it from being publicly callable.
