[ros-dev] Use kernel types in include files?

[Jun Koi]

Hi,

I am working on a project to parse the Windows image file. To do that,
I must understand the structure of some Windows components, like
_EPROCESS. So I took some headers from ReactOS, and write *userland*
code like below:

----
#include <pstypes.h>
#include <stdio.h>

int main()
{
    printf("size of EPROCESS: %d\n", sizeof(struct _EPROCESS));
    return 0;
}
----

The I got the problem: g++ reported that _EPROCESS is incomplete.

Clearly this means it doesnt see the structure _EPROCESS, so I took a
closer look, and found that _EPROCESS is not defined in user-mode
(NTOS_MODE_USER). I tried to fix it by putting

#undef NTOS_MODE_USER

in front of #include <pstypes>, but that doesnt help.

Anybody please tell me if there is any way to fix this?

I think I can fix that by modifying the original headers. but that is
way too ugly.

Many thanks,
Jun
