RtlStringCchPrintfW in Windows2000

NTDEV
1

Hi,

I have tiny driver derived from ‘portio’ of WDK(6000) that works in XP.
Today I tried to load the driver in Windows2000 (compiled for Windows 2000)
and it crashed with STOP: c0000263 {Driver Entry Point Not Found}; it did’nt
find _vsnwprintf in ntoskrnl.exe. If I don’t use RtlStringCchPrintfW then
the driver works. I’d like to use that API, any suggestions to make it work
both for Windows200/XP?

Thanks,
Hakim

according to wdk\inc\ddk\ntstrsafe.h:

// The following steps are *REQUIRED* if ntstrsafe.h is used for drivers on:
// Windows 2000
// Windows Millennium Edition
// Windows 98 Second Edition
// Windows 98
//
// 1. #define NTSTRSAFE_LIB before including the ntstrsafe.h header file.
// 2. Add ntstrsafe.lib to the TARGET_LIBS line in SOURCES
//
// Drivers running on XP and later can skip these steps to create a smaller
// driver by running the functions inline.
