[zeromq-dev] zmsg.hpp

[Ilja Golshtein]

Hello,

a couple of questions about zmsg.hpp , mentioned in zguide.

1. Where is the official source of it? What is the status of the code?

2. In a version I've got in zeromq maillist I can see
==
         zmq::message_t message(0);
         try {
            if (!socket.recv(&message, 0)) {
               return false;
            }
         } catch (zmq::error_t error) {
            printf("E: %s\n", error.what());
            return false;
         }
         ustring data = (unsigned char*) message.data();
==
where ustring is
==
typedef std::basic_string<unsigned char> ustring;
==

The question is if it reliable to assume zeromq message is ASCIIZ, what
we effectively do in the latest line I've quoted?
Why we do this 
==
data[message.size()] = 0
==
afterwards?

3. Is it good idea to do extra copy keeping message parts? 
I mean if
==
std::vector<std::basic_string<unsigned char> > m_part_data;
==
reasonable storing approach?


Thanks.
