Wait, I misread your previous post. The compiler uses cdecl by default, so unless you specify NTAPI then you get cdecl

(I blindly followed the headers). I just wanna understand it before I revert. What I don't get is that if I were to write code which uses this API, I would write my callbacks without NTAPI as per the headers. I'm guessing most other devs would too. So how are people building with cdecl and being called by Windows with stdcall without stack issues? In fact, explicitly going against the DDK and adding NTAPI to your callbacks would generate a compiler warning.

So unless there is a __cdecl in the DDK definition, your change is most likely wrong. PS: I guess it's time to finally autogenerate headers at build time, so that nobody even gets tempted to hack ntifs/ntddk/wdm/winnt directly instead of adding stuff to XDK... :) Timo Am 05.05.2015 um 21:41 schrieb Ged Murphy: > Well this is a weird one, the DDK says these callbacks are cdecl > (missing NTAPI) and anyone building against the DDK will obviously declare their callbacks to match this convention.
