       - prototype in malloc.h

       - walks the heap for each entry specified and returns information
         about the entry via the other fields of the _heapinfo structure
       - heapwalk maps to the other functions depending on memory model
       - returns one of the following:

         _HEAPOK       heap is ok
         _HEAPBADBEGIN initials allocation header couldn't be found
         _HEAPBADNODE  heap/node has been damaged
         _HEAPEMPTY    heap has not been initialized
         _HEAPBADPTR   parameter does not contain valid pointer to heap
         _HEAPEND      end of help found w/o problem

       struct _heapinfo
          int    _far *_pentry;        - heap entry pointer
          size_t _size;                - size of heap entry
          int    _useflag;             - entry in use return value

       - see   heapchk()   heapset()
