23 Currently, this dynamic array abstract data type can accommodate only
24 2^QB_ARRAY_MAX_INDEX_BITS elements, and with standard zero-based index‐
25 ing, this gives a valid index range [0, QB_ARRAY_MAX_ELEMENTS), where
26 the notation denotes the beginning of the interval is included and the
27 end is excluded. In other words, client space shall avoid a pitfall of
28 relying solely on the type of max_elements parameter to qb_array_create
29 and/or of idx parameter to qb_array_index (these types conflict, any‐
30 way).
