    Is there any difference between two functions defined below ?

    static int my_func() ;

    int my_func() ;

    Thanks in advance!

  2. Your friendly C textbook should have already explained this.
    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:
    static int foo() {
    return 0;
    int bar() {
    return 0;
    (both files look the same)
    you would get "function already defined" errors for bar, but foo would
    compile absolutely OK.
