public class FileAndChunks {
    public string filename;
    public int64 size;
}

int sort_by_size(FileAndChunks o1, FileAndChunks o2)
{
        return  (int) (o1.size > o2.size) - (int) (o1.size < o2.size);
}


public static void main (string[] args) {
        Array<FileAndChunks> list = new Array<FileAndChunks>();
        FileAndChunks f;

        f = new FileAndChunks();
        f.size = 8620258;
        f.filename = "Sd9YYxjP";
        list.append_val(f);
        f = new FileAndChunks();
        f.size = 6839026;
        f.filename = "ybJI6spa";

                print ("%s => %d\n", f.filename, (int) f.size);
        }

        list.sort_with_data(sort_by_size);

        print ("\n\nAFTER\n");
