The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the IO.H header at
d:\th\minkernel\ntos\inc
and draws from it the following type definition:
| Line Number | Type |
|---|---|
| 51 | struct _DUMP_STACK_CONTEXT |
| 264 | struct _IO_TIMER |
| 277 | struct _IO_CLIENT_EXTENSION |
The header IO.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
