std::wcscpy

From cppreference.com
< cpplrm; | stringlrm; | wide
Defined in header <cwchar>
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.

Parameters

dest - pointer to the wide character array to copy to
src - pointer to the null-terminated wide string to copy from

Return value

dest

Example

#include <iostream>
#include <cwchar>
#include <memory>
#include <clocale>

int main()
{
    const wchar_t* src = L" means dog";
//  src[0] = L''; // 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'';
    std::setlocale(LC_ALL, "en_US.utf8");
    std::wcout.imbue(std::locale(""));
    std::wcout << src << '\n' << dst.get() << '\n';
}

Output:

 means dog
 means dog
