Question in Heap code (/score/inline/heap.inl)

[Kim, Jeong-Hwan]

Hi, everyone
I have a question in /score/inline/heap.inl.
The routine for returning the head or the tail of HEAP has a following code.
Is the code right ?
Why is the pointer mark attached to the heap argument ?
It means "&(the_heap->start)" and &(the_heap->tail).
Then, does the return value point the tail or start of the block list right ???

Aren't the start and final variables pointers themselves ?




RTEMS_INLINE_ROUTINE Heap_Block *_Heap_Head (
  Heap_Control *the_heap
)
{
  return (Heap_Block *)&the_heap->start;
}

/*PAGE
*
*  _Heap_Tail
*
*  DESCRIPTION:
*
*  This function returns the tail of the specified heap.
*/

RTEMS_INLINE_ROUTINE Heap_Block *_Heap_Tail (
  Heap_Control *the_heap
)
{
  return (Heap_Block *)&the_heap->final;
}
