< cpp | string | char traits
| static char_type* copy( char_type* dest, const char_type* src, std::size_t count ); |
(constexpr since C++20) | |
Copies count characters from the character string pointed to by src to the character string pointed to by dest.
If [dest, dest + count) and [src, src + count) overlap, the behavior is undefined.
See CharTraits for the general requirements on character traits for X::copy.
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 in count.
