Hi Mlobo,

to accomplish your goal you have to set up a Remote Adapter Infrastructure, following the principles depicted in this document.

Basically, you have to create one or more processes which open a TCP communication with Lightstreamer Server and start the interaction by exchanging commands as required by the ARI protocol.

It is possible to implement a Remote Adapter for any language that supports socket programming, and C (in any its implementation) obviously does. Here the full list of Remote Adapter examples in different languages and platforms.

Please get back to us for any doubt.
