          function in an object

          Return the file name of the object that defines the function
          `str' in object `ob'. The returned value can be other than
          `file_name(ob)' if the function is defined by an inherited
          object.

          0 is returned if the function was not defined.

          Note that function_exists() does not check shadows.
