 Message        The declaration of <function> has an empty parameter
                list.  If the function has parameters, they should be
                declared here; if it has no parameters, "void" should
                be specified in the parameter list.

 Description    The recommended way to declare a function that takes
                no parameters is to use "void" in the parameter list.

 User Action    Make the recommended change.
