| static char_type* move( char_type* dest, const char_type* src, std::size_t count ); |
(constexpr since C++20) | |
Copies count characters from the character string pointed to by src to the character string pointed to by dest.
Performs correctly even if the ranges [src, src + count) and [dest, dest + count) overlap.
See CharTraits for the general requirements on character traits for X::move.

|---|---|---|---|
| LWG 7 | C++98 | the copy was guaranteed to perform correctly if src is in [dest, dest + count), but not the otherway round (i.e. dest is in [src, src + count))
