Have a nice day.

But it seems that there are some problems in this line

    rt = libparser.parse(byref(post), src)
    return (
        rt,
        string_at(post.title, post.tsz),
        string_at(post.tpic, post.tpsz),
        post.body
    )

They are all wrong result. Such as rt is -1, title and body is None.
