41 Null AV pointer.

46 Same as C<L</av_top_index>> or C<L</av_tindex>>.
48 =for apidoc Cm|SSize_t|AvFILLp|AV* av
50 If the array C<av> is empty, this returns -1; otherwise it returns the maximum
51 value of the indices of all the array elements which are currently defined in
52 C<av>. It does not handle magic, hence the C<p> private indication in its name.
54 =for apidoc Am|SV**|AvARRAY|AV* av
55 Returns a pointer to the AV's internal SV* array.
57 This is useful for doing pointer arithmetic on the array.
58 If all you need is to look up an array element, then prefer C<av_fetch>.
