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).

Parameters

dest	-	pointer to a character string to copy to
src	-	pointer to a character string to copy from
count	-	the number of characters to copy

Return value

dest

Exceptions

Throws nothing.

Complexity

Linear.
