Difficulty Reading/Implementing "GDNative C Example" Code

Hello Godot Community,

I have been through the GDNative C Example tutorial, but have difficulty applying the knowledge gained through it to my own C/Godot project. I wouldn't complain, except that this has prevented me from working in C before. I'm relatively new to C, but would like to learn more through my code.

I didn't know exactly how to solve this. If there were a pseudo-code version of the GDNative C and C++ Examples, maybe? Something along the same lines would really improve readability.

Thank you,
humble junior dev
