Implementing Vulkan in SDL2 with C programming language

Hello there,
I’m new to SDL and Vulkan programming so i started following the tutorial on
However at the point where you have to make an extension to the window i failed. I saw that SDL2 has a function for that (, however it makes use of some C++ features such as vector. Can someone help me going beyond this? I would be thankful for every ressource you can offer me for learning all of this. It must not be limited to my question, so feel free to send me any ressource you think i can benefit from. Thanks :smiley:
