dictNext - search for next value in dictionary.

       dict - dictionary to iterate over.
       id - pointer to identifier of last item found, or
       pointer to NULL to retrieve first.
       plock - place for value lock (or NULL).

       Can  be used to iterate through values in the dictionary.  The order is the order of the hash of the ids,
       which isn't usefully externally.  Will return the value if found, or NULL if not.   If  <plock>  is  non-
       NULL,  then  the lock returned in <plock> will be associated with the returned value.  Until this lock is
       passed to dictReleaseLock(),  the  value  will  not  be  passed  to  the  dictCleanupFunc  callback  (see
       dictCleanup()).

       MT-Level: Safe if <dict> thread-safe.

       plock - set to value lock.
       id - pointer to id of found value
