Dear All. Is there a C client program that can make me send and receive information from ROS server? What I need it is that I want to use C program to develop some program and use it as a client of ROS server. Best regards. Zhenli zhenli.lu@ua.pt

Try this tutorial:

Writing a Simple Publisher and Subscriber (C++))

It goes over writing a pair of minimal c++ programs that send each other a message using the ROS interface

Thank you very much for your email. That is a good way for c++ program. Since we have some work is done in C program and makefile, we want a minimal Publisher and Subscriber in C language, thus I can intergate it into my software package, otherwise, I must rewrite my program from C+makefile to C++ + cmakelists.txt. Best regards. Zhenli

Since C++ is a superset of C (well, for most practical purposes anyway), you should be able to wrap your existing code in ROS relatively easily. There is no simpler API for ROS, and use of the ROS build mechanism is highly recommended.

If you have existing C code that you want to reuse, you might consider packaging it as a library and then calling that library from a ROS node written in C++
