std::char_traits<CharT>::copy

From cppreference.com
< cpp‎ | string‎ | char traits
static char_type* copy( char_type* dest, const char_type* src, std::size_t count );
(until C++20)
static constexpr char_type* copy( char_type* dest, const char_type* src, std::size_t count );
(since C++20)

Copies count characters from the character string pointed to by src to the character string pointed to by dest.

Formally, for each i in [0, count), performs assign(src[i], dest[i]).

The behavior is undefined if copied character ranges overlap, i.e. src is in [dest, dest + count).
