Shouldn't the last one be something like ~(ULONGLONG)0 instead of
0xffffffff?

Sounds good, but in that case shouldn't I also change the one for UINT
to something like ~(UINT)0?

Well, yes, ~0u is usually a better choice than 0xffffffff, but that's
more of a cosmetic issue, unlike the long long case.
