 Null AV pointer.

+=for apidoc Am|SSize_t|AvFILL|AV* av
+Same as C<L</av_top_index>> or C<L</av_tindex>>.

-=for apidoc Am|int|AvFILL|AV* av
-Same as C<av_top_index()>.  Deprecated, use C<av_top_index()> instead.
+If the array C<av> is empty, this returns -1; otherwise it returns the maximum
+value of the indices of all the array elements which are currently defined in
+C<av>.  It does not handle magic, hence the C<p> private indication in its name.
 
-=for apidoc Am|int|av_tindex|AV* av
-Same as C<av_top_index()>.
+=for apidoc Am|SV**|AvARRAY|AV* av
+Returns a pointer to the AV's internal SV* array.
+
+This is useful for doing pointer arithmetic on the array.
+If all you need is to look up an array element, then prefer C<av_fetch>.
