Скрипт архивирование на USB (панель СП3хх)
Добрый день! На основе примера Евгения Кислова переделываю скрипт под свои нужды.
Задача состоит в том чтобы имя файла формировалось с помощью функции snprintf и состояло из даты и времени формата ддммггггччммсс.csv
snprintf(filename,(FILENAMESIZE+1), "%02d%02d%04d%02d%02d%02d.csv", wDay, wMonth, wYear, wHour, wMinute, wSecond);
Происходит ошибка открытия файла. Друзья, что у меня не верно? Если ли ошибка в длине имени файла FILENAMESIZE = 18?
