IoGetRequestorProcessId and ntifs.h

I wanted to use IoGetRequestorProcessId, but only including ntddk.h gives:

error C3861: ‘IoGetRequestorProcessId’: identifier not found

I found that this was in ntifs.h, but including ntifs.h gives

1>c:\winddk\7600.16385.0\inc\ddk\ntifs.h(85) : error C2371:
‘PEPROCESS’ : redefinition; different basic types
1>c:\winddk\7600.16385.0\inc\ddk\ntifs.h(86) : error C2371: ‘PETHREAD’
: redefinition; different basic types

despite the following: “Starting with the Windows Vista version of the
WDK, Wdm.h, Ntddk.h, and Ntifs.h are organized hierarchically and do
not contain duplicate information”

Anybody know what’s going on? Thanks in advance.

You included ntifs.h and ntddk.h just include ntifs.h
