for static functions in C++ go through: http://www.codersource.net/cpp_tutorial_static_functions.html and in C a static function has a name visible in that translation unit only. A normal function has a name visible across the entire program. If you were to have two source files with the undermentioned code: Code: static int fun() { return 0; } int morefun() { return 0; } you would get "function already defined" errors for function morefun( ), but fun( ) would compile successfully . a static function can only be called in the translation unit in which it is defined... hence a call to a static function from a file where it has not been defined will give a compilation error. friend why don't you try a bit of googling before u post a question..these kind of information is very very easily available on the net.
