Heap constants

Syntax

#include <malloc.h>

Remarks

These constants give the return value indicating status of the heap.

Constant	Meaning
_HEAPBADBEGIN	Initial header information wasn't found or was invalid.
_HEAPBADNODE	Bad node was found, or heap is damaged.
_HEAPBADPTR	_pentry field of _HEAPINFO structure doesn't contain valid pointer into heap (_heapwalk routine only).
_HEAPEMPTY	Heap hasn't been initialized.
_HEAPEND	End of heap was reached successfully (_heapwalk routine only).
_HEAPOK	Heap is consistent (_heapset and _heapchk routines only). No errors so far; _HEAPINFO structure contains information about next entry (_heapwalk routine only).
