std::char_traits<CharT>::copy
< 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 ); |

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.
