So I would suggest the following conventions:
- static functions: private
- functions defined but not declared (even through an extern): 'local'
- functions defined and declared in corresponding header: public
- functions defined and declared with extern somewhere else: global?
Do we need more than just public/private?

If I have
a function 'int f1(void)' defined in 'file1.c'.
If I declared at the begining of another file 'file2.c' : 'extern
int f1(void);' , and use it later in this file (without declaring
it in a '.h' file) .
Will it work ?
He he, 'extern' is a way to say that the function is defined
somewhere else. It is therefore public.

Hi Cyrille,
This is not quite exact. A static function is a function that is
visible only in the file that defines it. It is true that it could
be assimilated as a private function. But the privacy is also
obtained by not having the function signature in the .h file.
Contrary to Java, there is no such a keyword in C that says if a
function is private a or public, but there is a number of
technical conventions.

Hello,
A thing I want to do when importing C code in moose , is to see if
a function is Private or Public.
After reading some documentations about C, a private function ( A
function that can't be used outside the module in which it's
defined) is a function declared with 'Static'. Am I wrong ?
If this is ok, the first thing is:
=> FAMIXFunction > isPublic just check if the function is called
outside the module. This does not really correspond to the
description above.
the secong thing is:
=> How can I see if a function is declared with 'static' ?
For the moment I can have this information in the signatiure of
the function. But to retrieve that, I have to parse the string.
