Dynamic run-time linking in kernel mode ?

NTDEV
1

Hi,

In order to fulfil WHQL requirements I have to use MmGetSystemAddressForMdlSafe on Windows XP which is actually a macro that calls MmMapLockedPagesSpecifyCache. However, this function is not available on Win98SE and the binary will not load.

Is there any other (and more elegant) solution than producing 2 separate binaries?
One idea I have is to implement something like dynamic linking at run-time. Does anyone know if this is possible?

The kernel-mode equivalent of GetProcAddress. It has been in the DDK
header files for a while, but not documented in the help file.

NTKERNELAPI
PVOID
MmGetSystemRoutineAddress (
IN PUNICODE_STRING SystemRoutineName
);
