The act of declaring a function static in no way affects the return value of
the function.  It merely restricts the scope of the function name to the
file in which it lives.  That is, the name of the function is NOT an external
symbol and may not be referenced by functions in a seperately compiled unit.

Note that this is the only way to restrict the scope of a function name.
Without being defined 'static' all function names are external symbols.


Hope this helps,
