The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the OBP.H header at
d:\th\minkernel\ntos\ob
and draws from it the following type definitions:
| Line Number | Type |
|---|---|
| 317 | struct _OBJECT_HEADER_HANDLE_REVOCATION_INFO |
| 629 | struct _OBJECT_REF_TRACE |
| 639 | struct _OBJECT_REF_STACK_INFO |
| 652 | struct _OBJECT_REF_INFO |
| 668 | struct _STACK_TABLE |
| 962 | struct _OBP_SYSTEM_DOS_DEVICE_STATE |
| 1147 | struct _OBP_LOOKUP_CONTEXT |
| 2258 | struct _OBP_SILODRIVERSTATE |
The header OBP.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
