Solution: move private classes to separate header

I'll do this now.

This library looks amazing and exactly what I am looking for?

• Does this library support pub / sub?
• Does this library require threading?
• Does this library require a memory manager?

In general, what features are supported and what does the library require to operate?

Thanks a ton!

Solution: add test case in each class and then run class selftests in zmtp_selftest.c

The transport is specified in the API rather than the endpoints. This is problematic for e.g. connecting a socket to multiple endpoints taken from a configuration file. The caller would have to parse the endpoints themselves to use the correct API call.

Solution: implement transport prefix in endpoints, and provide single 'bind' and 'connect' methods for all supported transports.

Solution: take zlist and zhash containers from CZMQ and rename for project.

Solution: implement abstract IPC endpoints as libzmq does, e.g.:

@/zpipes/local

The usually pattern is _new/_connect/_destroy. However now the connect method acts as a constructor.

Solution: connect should take a self reference. _new should not take an fd. If we want to make things very simple, _new can take an endpoint as argument, and do the connect in one step (this would be fine for now).

Hi, very nice project but I think is very important one sample hellow word for pub, sub, etc.

Since there's no server-side sockets, we cannot make proper test cases without resorting to either libzmq or raw TCP.

Solution: implement basic server-side support (bind and accept incoming connections).

we have some interest in an embedded client which would need to do both DEALER and XSUB (NB @zhivko)

it turns out the dealer socket works just fine with an XSUB publisher, see testxsub.c in https://github.com/mhaberler/libzmtp/commits/xpub

happy to take recommendations what to do with this

I see how I could do a ROUTER pthread for a dealer selftest
I do not see how I could do a XPUB pthread - unclear how to manage subscriptions

is it worth writing zmtp_router.c, zmtp_xsub.c classes?
