戻り値
do_out(state, from, from_end, from_next, to, to_end, to_next)
例
#include <iostream>
#include <locale>
#include <cwchar>
int main()
{
using codecvt_t = std::codecvt<wchar_t, char, std::mbstate_t>;
const auto& cv = std::use_facet<codecvt_t>(std::locale::classic());
const wchar_t from[] = L"abc";
char to[4] = {};
std::mbstate_t state{};
const wchar_t* from_next = nullptr;
char* to_next = nullptr;
codecvt_t::result r = cv.out(state, from, from + 3, from_next, to, to + 3, to_next);
*to_next = '\0';
std::cout << std::boolalpha << (r == codecvt_t::ok) << std::endl;
std::cout << to << std::endl;
