Ошибку-то покажите. Я могу максимум добавить, что операторы без rvalue в контейнере это friend контейнера и что в класс с полем i это:
struct SS {
int i[5] = { 1,2,3,4,5 };
};error C2666: "dte_utils::operator +": перегруженные функции имеют похожие преобразования?
умный указатель мне нужен для того, чтобы отслеживать, является ли функция выгруженной

}это не значит, что ReadFile гарантированно завершиться синхронно
