Functions working with memory can be faster if the operations are done on word-size blocks at a time rather than bytes. So if I’ll ever need a faster implementation, I can explore this further. See c - Understanding the source code of memcpy() - Stack Overflow.

Also somehow memcpy behaves like memmove on my machine (Kubuntu). Didn’t check on iMacs.
