I’ve been working on my networking C code, which currently can send messages from one Windows machine to another. Now I want to figure out how to send messages from a Windows machine to a Linux machine and vice versa. I would really appreciate if anyone could tell me a basic rundown of how you would do this in C.

I’ve been searching for a while but found no concrete answers on the subject.

Sorry if this question is stupid or poorly written, thanks for helping.
