In my opinion, memcpy() vs memmove() and What is the difference between memmove and memcpy? both cover the exact the same question. Normally I'd flag one of these as duplicate of the other.
However, in this case, both questions did get answers that a very comparable in quality, the question is clear in both questions, so I really cannot decide which one to flag. So the question appeared: should I be flagging one of these questions?
Can two identical questions coexist without being marked as duplicate?
