[zeromq-dev] Is the zmq_strerror method threadsafe?

Do you consider the method zmq_strerror to be threadsafe under ZMQ 3 and ZMQ 4?

Details for my question:
The zmq documentation does not state that zmq_strerror is threadsafe.
The Zmq codebase for both Zmq 3 and Zmq 4 calls strerror, not strerror_r.
The Linux man page for strerror indicates that it is not guaranteed to be threadsafe, whereas strerror_r is guaranteed threadsafe.  But often, the actual code implementation for strerror *is* threadsafe.

Note: Our current sw configuration requires one of RedHat Linux 5,6,7 and SuSe Linux 11, and ZeroMQ 3.2.3.7

Thx,
Michael Devereaux
