NAME

std::char_traits::copy - std::char_traits::copy

Synopsis

static char_type* copy( char_type* dest, const char_type* src, (until C++20)
std::size_t count );
static constexpr char_type* copy( char_type* dest, const char_type* (since C++20)
src, std::size_t count );

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.
