std::wcscpy
std::wcscpy
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"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:
犬 means dog 狗 means dog
