The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the NTOBAPI_X.H header at
d:\th.public.fre\internal\sdk\inc
and draws from it the following type definitions:
| Line Number | Type | Remarks |
|---|---|---|
| 75 | struct _OBJECT_NAME_INFORMATION | line 7216 in WDM.H |
| 97 | enum _OBJECT_INFORMATION_CLASS | line 12769 in NTIFS.H |
The header NTOBAPI_X.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
