converting from NTSTATUS code to Win32 error codes

NTDEV
1

Hi all

In my device driver I try to complete an IRP with a certain error code to
show the application what the problem is (i.e. STATUS_INVALID_HANDLE or
STATUS_ILLEGAL_INSTRUCTION). According to the appendix A from Peter
G.Viscarolas Driver book I should get the corresponding win32 error code,
if I call straight after the DeviceIoControl() function the GetLastError()
function. But it’s not like that, no matter which STATUS_… code I
choose, I always get the error code 2 (ERROR_FILE_NOT_FOUND) after calling
the GetLastError(), I checked the return code from the DeviceIoControl()
and it is really 0 (for error).

Does somebody has a clue what the problem could be?
Thanks for taking time
Daniel

You could save your driver’s error within the driver and instead of calling
GetLastError call the driver again to request it’s last error.

Well that is not such a good idea. Consider that this doubles the number
of transactions required. Consider also that you now have to correlate
the error condition with the original request.

The mapping between NT and win32 error codes is defined in KB article
Q113996.

In addition you can get extended status information, including the
original NT status code, from the operation, if you open the file for
asynchronous operations and use the overlapped structure.

However, the mapping from NT status to win32 works fine as far as I
know, so if the IO operation is returning ERROR_FILE_NOT_FOUND then the
NT status that you are setting in BOTH THE IRP AND AS THE RETURN VALUE
FROM YOUR DISPATCH ROUTINE maps to ERROR_FILE_NOT_FOUND.

I use the following routine: RtlNtStatusToDosError

It is now documented by MS due to some legal issues.

The even documented RtlUnwind - the engine which calls your __except()
handlers - which is surely funny, no sane developer will ever call
this function instead of RaiseException, thus no need (except the
attorney’s claims) for this internal routine to be documented.

RtlUnwind is documented for compiler writers and most of them, to my best
knowledge, are sane.
Also Numega DriverWorks uses RtlUnwind (and even RtlUnwind2 on IA64) to
implement C++ exception handling in kernel mode.

It is now documented by MS due to some legal issues.

The even documented RtlUnwind - the engine which calls your __except()
handlers - which is surely funny, no sane developer will ever call
this function instead of RaiseException, thus no need (except the
attorney’s claims) for this internal routine to be documented.
