 Message        The function "<name>" has an implicit return type of
                int, but no value is given in this return statement.

 Description    A function that has an implicit return type of int
                contains a return statement that is missing a return
                value.  Therefore, the returned value will be
                undefined.  This might not have been what you
                intended.

 User Action    Supply a return value for the return statement or
                define the function with a void return type.
