If yes, what is the sense of making a non-member function a static function? Can these functions only access static variables?

If yes, what is the sense of making a non-member function a static function? Can these functions only access static variables? Yes they do, but it's a completely different meaning of the keyword static. A non-member static function cannot be accessed outside of the translation unit in which it appears. That is the meaning of static when applied to a function or variable outside of any classes or functions. A translation unit is all the code in a single compilation, normally this means one source file and the headers it includes. john Back to top Alf P.

Quote: If yes, what is the sense of making a non-member function a static function? The word 'static' has a different effect when applied to a non-member function. The non-member function is already a static function. What 'static' does to that function is give it internal linkage so that it won't be visible outside the compilation unit -- i.e., (over-simplified) the linker will not see it. This use of 'static' is deprecated, and imposes the limitation that the function cannot be used as a template argument. The modern way is to instead place the function in an anonymous namespace, but for convenience or simply out of habit many (including me) prefer to use 'static'.

Quote: If yes, what is the sense of making a non-member function a static function? Can these functions only access static variables? No. A static function can only be called from the translation unit it is defined in. It has internal instead of external linkage, just like static variables in the same scope do.
