Can I call memcpy() and memmove() with “number of bytes” set to zero?
...ssembly, and try to copy most of the bits using the native word size (e.g. uint32_t on x86), but that doesn't change the substance of the answer: it's a while loop that doesn't need great calculations before starting, so the check is already done.
