The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the HEAPIDX.H header at
d:\th\minkernel\ntos\rtl
and draws from it the following type definition:
| Line Number | Type |
|---|---|
| 57 | struct _HEAP_LIST_LOOKUP |
The header HEAPIDX.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
