std::char_traits::copy(3) | C++ Standard Libary | std::char_traits::copy(3) |
NAME¶
std::char_traits::copy - std::char_traits::copy
Synopsis¶
static char_type* copy( char_type* dest, const char_type* src,
(until C++20)
std::size_t count );
static constexpr char_type* copy( char_type* dest, const char_type* (since
C++20)
src, std::size_t count );
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 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¶
Throws nothing.
Complexity¶
Linear.
