[zeromq-dev] more on c++ api

[Burak Arslan]

 hi,

i got a few ideas that would be nice to have in the c++ api:

1) zmq.hpp has

#include <assert.h>
#include <string.h>

in the beginning. converting them to

#include <cassert>
#include <cstring>

would be better in line with c++ conventions, and in case of cstring
header, would help keep the default namespace clean.

2) providing message_t (copy) constructors as such;

message_t(const std::vector<uint8_t> &) // for binary data
message_t(const std::string &) // for strings

will let us call socket.send("blah") or
socket.send(vector_with_binary_data);

3) providing stream operators

zmq::socket_t &operator<<(zmq::socket_t &, zmq::message_t &);
zmq::socket_t &operator>>(zmq::socket_t &, zmq::message_t &);

or even:

std::ostream &operator<<(std::ostream &, zmq::message_t &);

would be nice.

4) providing a multipart_message_t class and adding support for it to
socket's relevant functions would make the api more elegant.

i can probably work on those if you'd be willing to merge them before 3.x.

best,
burak
