[zeromq-dev] zmq errno 156384763

[Pieter Hintjens]

Hi Rakesh,

Thanks for the code example, that shows the actual error.

You're using "1" as the value for the more option, but you should use
ZMQ_SNDMORE (which actually has the value 2, but please don't use the
numeric values for constants since they can change arbitrarily).
