std::char_traits::move, std::char_traits::move, std::char_traits::move, std::char_traits::move, std::char_traits::move (original) (raw)
| static char_type* move( 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.
Performs correctly even if the ranges [src, src + count) and [dest, dest + count) overlap.
See CharTraits for the general requirements on character traits for X::move.
[edit] 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 |
[edit] Return value
dest
[edit] Exceptions
Throws nothing.
[edit] Complexity
Linear in count.
[edit] Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 7 | C++98 | the copy was guaranteed to perform correctly ifsrc is in [dest, dest + count), but not the otherway round (i.e. dest is in [src, src + count)) | also guaranteed |
