See Hwk4/Deque.h, which states:

  // The following functions are the only means of accessing a Deque data
  // structure.  Each requires a pointer to a Deque variable in case it needs
  // to modify the value of that variable (or more generally for uniformity).
  // Each returns the status of the operation, either true (= success) or false
  // (= failure; e.g., an invalid argument, an inconsistent Deque object, or a
  // NULL return from malloc() / realloc()).
