I think the person who asked about this knows what a static function is, he
just wanted to know why a lot of palm code uses them a lot.
So actually it does have to do with palm. They answer is in the archives,
but here "my" answer.
>From what I hear older version of CW (this is stuff that I just remember
reading from the list) use to give some kind of warning/error if certain
function were not static. People just still do it for no reason.
Here are a couple of people's explanations

That really has nothing to do with Palm; it is a C question.
Declaring a function static means it can't be called from code that is
defined in another file. If you want to use multiple .c files and call a
function in one file from another file, then it can't be static. In that
case, the function is declared in a header file which is shared by all the c
files that use that function. For a simple application, you may want to
include everything in one file, so you declare the functions static to save
you the trouble of adding a separate header file to declare the functions.
If, by any chance, you happen to be a Pascal programmer, think of it this
way: The declaration (which is usually in a header file) is what Pascal
referred to as a "forward declaration", which allows for the declaration of
a function to be separated from the definition of that function.
Back to C... If you omit the word static, and there is no header file that
declares the function, then when the compiler encounters the function
definition, it complains.
Note that in a Palm app, the PilotMain() function is *not* declared static.
That is because PilotMain is the main entry point into your code and it is
called by the OS, which is obviously outside of your file.
