The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the ACTION.H header at
d:\th\minkernel\ntos\io\pnpmgr
and draws from it the following type definitions:
| Line Number | Type |
|---|---|
| 31 | enum _PNP_DEVICE_ACTION_REQUEST |
| 60 | struct _PNP_DEVICE_ACTION_ENTRY |
The header ACTION.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
