The public symbol file NTKRPAMP.PDB for the original release of Windows 10 tells that the kernel is built with the IOMGR.H header at
d:\th\minkernel\ntos\io\iomgr
and draws from it the following type definitions:
| Line Number | Type |
|---|---|
| 112 | struct _RELATIVE_SYMLINK_INFO |
| 142 | enum _TRANSFER_TYPE |
| 228 | struct _IO_WORKITEM |
| 258 | struct _DUMMY_FILE_OBJECT |
| 276 | struct _OPEN_PACKET |
| 625 | enum _IOP_PRIORITY_HINT |
| 653 | enum _FILE_OBJECT_EXTENSION_TYPE |
| 668 | struct _IOP_FILE_OBJECT_EXTENSION |
| 749 | struct _IOP_IRP_EXTENSION |
| 4167 | struct _IOP_IRP_EXTENSION_STATUS |
The header IOMGR.H is not known in any Device Driver Kit (DDK) or Windows Driver Kit (WDK).
