Message        The last statement in non-void function "<name>" is
                not a return statement.

 Description    This message indicates that a function with an
                implicit return type of it does not end with a return
                statement.  If function execution reaches the end of
                the function, the implied return statement that
                executes will return an undefined value.  This might
                not have been what you intended.

 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.
