You mean like wrapping libzmq in such a way that the wrapper converts
errnos into return codes? That seems doable.
Btw, Linux kernel system of returning int from a function with negative
values reserved for errors seems to be handy as well:

Heh. Nice way of looking at it :)

A-ha. That's what you mean. To do that we should gradually change the
internal implementation of 0MQ to use return values instead of errnos
everwhere. Adding a new safe API on top would be the final touch.

Have you run the ./autogen.sh step?

You can find out by grepping the source code for ZMQ_HAVE_* macros.
These are defined by autoconfig.
