- *  _Heap_Extend
- *
- *  This routine grows the_heap memory area using the size bytes which

- *
- *  Input parameters:
- *    the_heap          - pointer to heap header.
- *    starting_address  - pointer to the memory area.
- *    size              - size in bytes of the memory block to allocate.
- *
- *  Output parameters:
- *    *amount_extended  - amount of memory added to the_heap
