GNAT Heap_Sort_A g-hesora ads (GNAT Reference Manual)

### 13.76 `GNAT.Heap_Sort_A` (`g-hesora.ads`) ¶

Provides a general implementation of heap sort usable for sorting arbitrary data items. Move and comparison procedures are provided by passing access-to-procedure values. The algorithm used is a modified heap sort that performs approximately N*log(N) comparisons in the worst case. This differs from `GNAT.Heap_Sort` in having a less convenient interface, but may be slightly more efficient.
