All of the standard C string functions I use are exported by
ntoskrnl.exe. If their implementations were broken somehow, Microsoft
would have made this loud and clear to the driver community a long time
ago. And if somebody wants to use something that isn’t there, he can
easily find a hundred thousand implementations on the web, not to
mention in the CRT source that ships with VC6/VC7. If that person isn’t
smart enough to adapt the code he finds to follow the few simple rules
necessary to run safely in KM (no large locals, etc.), he shouldn’t be
writing drivers in the first place. This isn’t rocket science guys.

driver?In a compiler that’s attached to a DDK and that has no other objective
besides building drivers, it’d make more sense to me if string.h was
kernel-side safe.Alberto.

and its routines over string.h. Unfortunately, it neither has an sscanf or
a strtok
equivalents that the original request asked for.Don Burn (MVP, Windows DDK)
