[zeromq-dev] How to get client's identity

[Diego Fons]

Hi,

ZMQ_IDENTITY is used only with DEALER socket. You can not retrive client
information with PUSH/PULL sockets (they are not implemented for this).

You can:
1) Re-implement your application to use DEALER/ROUTER or
2) Implement an abstraction layer that provides client identification (ie.
build your own protocol).

I'd choose the first one, but I don't know the main purpose of the
application.

Regards.
