VMS Help CC, Messages, VOIDRETURN1  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        The function "<name>" has return type void.  The
                return statement must not specify a return value even
                if the return expression has void type.

 Description    The current function was declared with a void return
                type.  Although some C compilers allow such a
                function to return a void expression, this is a
                violation of the C standard and may not be portable.

 User Action    Modify the program so that the return statement does
                not specify a return value.
