wchar_t *wcscpy( wchar_t *dest, const wchar_t *src ); |
Copies the wide string pointed to by src (including the terminating null wide character) to wide character array pointed to by dest.
If the strings overlap, the behavior is undefined.
| dest | - | pointer to the wide character array to copy to |
| src | - | pointer to the null-terminated wide string to copy from |
dest.

int main()
{
const wchar_t* src = L"犬 means dog";
// src[0] = L'狗'; // can't modify string literal
auto dst = std::make_unique<wchar_t[]>(std::wcslen(src)+1); // +1 for the null
std::wcscpy(dst.get(), src);
dst[0] = L'狗';
std::setlocale(LC_ALL, "en_US.utf8");
std::wcout.imbue(std::locale(""));
std::wcout << src << '\n' << dst.get() << '\n';
}Output:
