[zeromq-dev] How to do zero-copy multi-part messages without transfering the ownership of the data to ZMQ?

[Stephan Opfer]

Hi,

I would like to do what is described in this tutorial here: http://zeromq.org/blog:zero-copy

But, I don't like to transfer the ownership to ZMQ, because it will delete the data when the message is sent.

My application is more like this:

Several autonomous robots inform each other from each other from time to time about the results of some calculuations, e.g., path planning results.

These results are created for further processing and need to be kept in the ownership of the process itself. They can be send with zero-copy, because the wont be altered anymore, but should not be deleted.

Any suggestions?

Greetings,

   Stephan
