Personally I think that a guint64 argument is better:
- then you don't have to worry about the caller giving you not enough bytes
(too many isn't much of a problem I guess)
- if you do need to cast the data into a guint64 later (don't think you need to
here), you don't need to worry about whether the bytes are aligned correctly
(some architectures require int or longer accesses to be aligned on a 32-bit
boundary)
