Container Device/Sink bug

[aris.basic@…]

i think write should be like this, otherwise if one seeks back (after writing to overwrite replace some data, number of bytes seeked back will be duplicated on the next write. (original line changed/replaced is commented out in code)

    std::streamsize write(const char_type* s, std::streamsize n)
    {
        using namespace std;
        std::streamsize result = 0;
        if (pos_ != container_.size()) {
            std::streamsize amt =
                static_cast<std::streamsize>(container_.size() - pos_);
            result = (min)(n, amt);
            std::copy(s, s + result, container_.begin() + pos_);
            pos_ += result;
        }
        if (result < n) {
            container_.insert(container_.end(), s + result, s + n);
            //container_.insert(container_.end(), s, s + n);
            pos_ = container_.size();
        }
        return n;
    }
