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.
