        The message format used by this function internally is as follows:

        [ident1,ident2,...,DELIM,HMAC,p_header,p_parent,p_content,
         buffer1,buffer2,...]

        The serialize/unserialize methods convert the nested message dict into this
        format.

        Parameters
        ----------

        stream : zmq.Socket or ZMQStream
            The socket-like object used to send the data.
        msg_or_type : str or Message/dict
            Normally, msg_or_type will be a msg_type unless a message is being
            sent more than once. If a header is supplied, this can be set to
            None and the msg_type will be pulled from the header.

        content : dict or None
            The content of the message (ignored if msg_or_type is a message).
        header : dict or None
            The header dict for the message (ignores if msg_to_type is a message).
        parent : Message or dict or None
            The parent or parent header describing the parent of this message
            (ignored if msg_or_type is a message).
        ident : bytes or list of bytes
            The zmq.IDENTITY routing path.
        subheader : dict or None
            Extra header keys for this message's header (ignored if msg_or_type
            is a message).
        buffers : list or None
            The already-serialized buffers to be appended to the message.
        track : bool
            Whether to track.  Only for use with Sockets, because ZMQStream
            objects cannot track messages.

        Returns
        -------
        msg : dict
            The constructed message.
        (msg,tracker) : (dict, MessageTracker)
            if track=True, then a 2-tuple will be returned,
            the first element being the constructed
            message, and the second being the MessageTracker
