RltGetVersionEx vs PsGetVersion

NTDEV
1

Hello, all:
I want get the os version(2k/ xp sp1/ xp sp2/ etc.) in my driver.
PsGetVersion can use both in 2k and xp, but it can not give me the
enough info(service pack mjor and minor) . RtlGetVersionEx is only
supported in xp and later.
How can I get the os version in my driver which can be work in
both 2k and xp ? thanks

First for XP and later you ought to think about use of RtlVerifyVersionInfo
if you want to be compatible with the application specifications for
certification at some point down the road.

Second, well, since the Rtl*Version* functions are not available on W2K,
hard luck :slight_smile: In your driver use MmGetSystemRoutineAddress to get the address
of the Rtl*Version* function if its available otherwise you are before WXP
and all you can do is call PsGetVersion with reduced information provided.

You should also watch out for VER_SET_CONDITION, which calls
VerSetConditionMask, which is also XP and later. VER_SET_CONDITION used
to compact the arguments into one ULONGLONG, but since it calls
VerSetConditionMask now, you can easily use MmGetSystemRoutineAddress
for it as well.

Both VER_SET_CONDITION and VerSetConditionMask are documented for UM and
the docs apply to KM as well in terms of functionality (obviously
exported from different binaries though).

If I remember, PsGetVersion returns a pointer to the Service
Pack banner string, from which you can easily retrieve the
Service Pack number. I coded something like this in the
BoundsChecker driver way back when, but I don’t remember the
details any longer.
