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 );
|
(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 the character ranges [dest, dest + count) and [src, src + count) overlap.
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.
