hi Samuel,
Thanks for the pointer. I was trying to use Rtl* functions, but if memcmp() works, that is great.

I have a couple of questions though that are not clear to me from the documentation:
1. how does memcmp() when the lengths are different? what is the length argument that we need to pass?
2. If the lengths are different, we should be passing the larger length, does memcmp() terminate when it sees the NUL ('\0') character? Obviously passing the smaller length would be wrong.

If memcmp() has the same limitations as RtlCompareMemory() then we need this function.

Thanks,
