How do I properly wrap everything in my Cpp app using smart pointers?

I still can't understand how to wrap SDL C destruction functions.

Here is the documentation and example code for using the smart pointer classes unique_ptr and shared_ptr in C++:
https://en.cppreference.com/w/cpp/memory/unique_ptr/unique_ptr.html
https://en.cppreference.com/w/cpp/memory/shared_ptr/shared_ptr.html

Specifically, this is the documentation for the constructors for these classes. You are going to want to reference the examples that use a custom deleter function. You should be able to just pass the function name for the SDL destructor in the same parameter you might use a lambda in.
