I am sure that the developers behind zmq are(or were) far more intelligent and better programmers than I will ever be, but I have to say that as a user I would never recommend it to anyone for the following reasons: 1. A lot of gotchas and surprising behavior. For example this: > To be more explicit: after calling zmq_send the socket may become readable (and vice versa) without triggering a read event on the file descriptor. 2. The library will assert internally without actually giving you any clues what did you do wrong as a user. I would rather spend some extra time in development by using pure sockets rather than the stress of debugging problems, arising from the above, later.
