The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the PO.H header at
d:\th\minkernel\ntos\inc
and draws from it the following type definitions:
| Line Number | Type |
|---|---|
| 264 | struct _PO_DIAG_STACK_RECORD |
| 530 | struct _PO_HIBER_PERF |
| 639 | struct PO_MEMORY_IMAGE |
| 838 | struct _DIAGNOSTIC_CONTEXT |
The header PO.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
