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 // Run this code #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 See also wcsncpy copies a certain amount of wide characters from one string to another (function) copies a certain amount of wide characters between two non- overlapping wmemcpy arrays (function) strcpy copies one string to another (function) http://cppreference.com 2022.07.31 std::wcscpy(3)
