Subject: Invalid argument/Inconsistent Deque object

In Deque.h, it says the functions must return false if the argument is invalid or if the Deque object is inconsistent, among other things. Is an argument invalid only if the passed in Deque is null? Also, how can we check if a Deque object is inconsistent?

Thanks
