RE: [Dev-C++] What is a static function

[Tomas D. <do...@vo...>]

Hi Albert,

Well, functions declared with static memory class
can't be used in (called from) another module (file) then the one they ar=
e
declared in. It is the same with variables.
Have a look at this...

   static void f(void);   // this global function and
   static int n;          // this global variable
                          // are visible only in the module they are
declared in

Have you got the idea? An easy stuff...

If you want to know what is all this for, just ask.

yes, you can use the memory block and free it, too, if you bring the hand=
ler
of the memory block out of your function.

it is created always, I deeply believe
functions like this are completely build before they are called

yeah!

Heh.
Have a good time.
