std::char_traits<CharT>::copy: std::char_traits<CharT>::copy

NAME

std::char_traits<CharT>::copy - std::char_traits<CharT>::copy

Synopsis

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 character from character string pointed to by src to 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

(none)

Complexity

Linear.
