 Message        Non-void function "<name>" does not contain a return
                statement.

 Description    This message indicates that a function with an
                explicit return type does not contain a return
                statement.  This message is not issued for functions
                with an implicit return type of int.  See message
                IMPFNCMSSNGRET.

 User Action    Consider declaring the function to be a void
                function.  If it is supposed to return a value, add a
                return statement with the value the function is to
                return.
