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