55 entries can be explicitly split into smaller entries, or storing ``NULL``

70 ``NULL`` entry.  There is no difference between an entry that has never

81 at that index is ``NULL``, you can use xa_insert() which
100 normal API will see this entry as containing ``NULL``.  If you do
104 want the entry to become ``NULL``, you should use xa_erase().
107 If all entries in the array are ``NULL``, the xa_empty() function
123 xa_get_mark().  If the entry is not ``NULL``, you can set a mark on it
154 ``NULL`` will mark the entry as being in use, like xa_reserve().

486 Storing ``NULL`` into any index of a multi-index entry will set the
487 entry at every index to ``NULL`` and dissolve the tie.  A multi-index
