[zeromq-dev] Easy way to send/recv messages?

Hi all,

Reading Pieter's manual to 0MQ messages here:


I've come to realise how complex the whole thing is.

Now imagine there would be API that'll look like this:

int zmq_send (void *s, const void *buf, size_t len, int flags);
int zmq_recv (void *s, void *buf, size_t len, int flags);

Note the ease of use and the fact that it maps 1:1 to POSIX socket API.

Existing zero-copy message API can then be provided as a separate set of 

int zmq_sendmsg (void *s, zmq_msg_t *msg, int flags);
int zmq_recvmsg (void *s, zmq_msg_t *msg, int flags);

The above would break backward compatibility so it's not an option now, 
however, it looks like something to keep in mind for the future.
