The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the RELATIONS.H header at
d:\th\minkernel\ntos\io\pnpmgr
and draws from it the following type definitions:
| Line Number | Type |
|---|---|
| 48 | enum IRPLOCK |
| 124 | struct _RELATION_LIST |
| 161 | struct _PENDING_RELATIONS_LIST_ENTRY |
The header RELATIONS.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
