[zeromq-dev] Support multipart with SNDMORE and RCVMORE?

[zhiguo zhao]

Hi, all.

     Please consider below items.
     I.
            If is a short msg, It can be handle in one time with zmq_send
and zmq_recv, This will match 80%.
    2.
           If to process a long message,(may be 1G size) and result is
short,(just like do a message digest), client can send more times with
SNDMORE, and server will reply only onces to get result,  2 plus 1 with
match 98%.

         CLIENT       -----------------------------------   SERVER
        send(msg_p1, MORE)      ->                           recv

 digest(msg_p1)
        send(msg_p2, MORE)      ->                           recv

 digest(msg_p2)
        send(msg_pn)      ->                                        recv

  mdvalue = digest_result(msg_pn)
            recv                             <----
send(mdvalue)
   3.
          If to process a long message and result is long too, just think
that do  3des-cbc encrypt a big file, It make me fool, I can't find a
solution.

         CLIENT       -----------------------------------   SERVER
        send(msg_p1, MORE)      ->                           recv

 encrypt(msg_p1) as part1
                  ?                            <-
send(e_msg_p1,[MORE])    will failed.

        send(msg_p2, MORE)      ->                           recv

       any advice to help me handle this.

 Thanks.
