[zeromq-dev] zmq_unbind fails on inproc?

[Pieter Hintjens]

Hi Chuck,

Thanks for making the test cases. What would be better, ENOENT or EINVAL?

The zmq_unbind and zmq_disconnect functions do not set zmq_errno to EINVAL when given an unknown endpoint like the documentation suggests. Instead, they set zmq_errno to ENOENT. I have opened issues for each of these and provided repro code too. I am not sure these are library bugs or documentation bugs. :)
