Thread: Static Function Understanding

I think I have the understanding correct, but just encase could someone confirm this for me.

In C, a static function is used to state that only the app/dll which contains the code for the function can use the function. So if I create a DLL only calls from inside the DLL can access the static function, and not the application using the DLL.

Best way I can think of helping explain, if the above doesn't make any sense.

DLL(contains static function)

APP using DLL can use all functions except for the static one(s).

-----------------------

I would just like to note, I'm slightly confused because by what I've read a static function in c++ is different to that of a static function in c. I just want to make sure I have the correct meaning for c.

It seems you've got it right.

A "static" function is only visible in the file where it is defined. See FAQ > static and extern? - Cprogramming.com for an example.

Bye, Andreas

Thank you for your reply. You just answered my next question about extern with functions as well

Functions that are declared with “static” before them are said to have internal linkage. When that keyword is omitted, they have external linkage and may be called by other translation units.
