[zeromq-dev] how to use ZeroMQ socket in multithread

[Charles Remes]

Both of those techniques are the recommended ways to use zeromq sockets in a multi-threaded application. I’m sorry that you don’t like those techniques, but they work very well.

The zmq_poll function is *not* thread-safe, so be very careful with it.

But the guide document says that ZeroMQ sockets are not thread safe.  How can I solve that problem. I don't want to create a new socket when sending some message through ZeroMQ every time.
