I think zmqc is a GREAT idea; thank you Zachary for the original concept, and thank you for placing it in the public domain!!!
In order to maximize adoption, I ported zmqc to C; you can find my initial version below. This is a raw first cut but it works with my basic (manual) unit tests. https://github.com/gonzus/zc I welcome any comments, patches, etc. I would like to license this using something like BSD or Apache; can anybody point me to the proper procedure?

One final query- can i access zeromq to send messages from shell scripts (Linux) and Command Line scripts(Windows)? That is what I would prefer to do- however I dont know if its possible.

It sounds like you are going to be exchanging small messages and not transferring very large chunks, you should be able to reduce memory usage of zmq. My first guess is tuning SND/RCVBUF SND/RCVHWM zmq socket options and using zmq_recv/zmq_send calls if you are very concerned and want the lowest memory usage. ________________________________ _______________________________________________ zeromq-dev mailing list zeromq-dev@lists.zeromq.org<mailto:zeromq-dev@lists.zeromq.org> http://lists.zeromq.org/mailman/listinfo/zeromq-dev _______________________________________________ zeromq-dev mailing list zeromq-dev@lists.zeromq.org<mailto:zeromq-dev@lists.zeromq.org> http://lists.zeromq.org/mailman/listinfo/zeromq-dev [cid:image001.jpg@01CE4FF7.606521C0] A.

Hence I want the process that sends messages via ZeroMQ to use as less RAM/CPU as possible. Yours sincerely, Arvind, Creatrix IT Soft.

The memory footprint of the process really depends on the implementation.

With the multiple language bindings available for ZeroMQ, I wish to use that language(for utilising ZeroMQ)- that uses the least possible RAM. And ideally I can compile/create the ready to run process on my machine, and then run it on any OS(including Linux-> Ubuntu/CentOS and Windows) and for different types of RAM/CPU configurations. I understand that ZeroMQ core will have to be installed/made available for use by my process. Any insights intot Yours sincerely, Arvind, Creatrix IT Soft.
