Re: General Linux c programming questions

On Linux both processes and threads are very lightweight. The only difference is that each process has its own separate address space, while threads share a common.

have Linux programming experience, but experience in programming the
controller in c, and Windows programming experience. I know Windows
multithreading programming.

Windows forces you to either uses a threaded model or an event driven model, because Windows processes are monstrous heavyweights. Linux process overhead is only a fraction of what it is under Windows. Application designs which naturally fit a multi-process model better can be directly implemented, as such, instead of having them shoehorned into a multi-threaded or an event-driven model.

Also I am looking for libraries for socket programming, and for
CANopen. I have heard that the CANbus is treated as a socket nowadays,
and that there is something called CANfestival.

If by sockets you are referring to networking sockets, no special libraries are required. Socket API is included in the standard C library.
