Initial C API #42

Open lu-zero opened 2 years ago

lu-zero commented 2 years ago

To start discussing on the API itself:

Function signatures dgc_{struct}_{action}(s: *mut Struct, args..., out: *mut *mut Out) -> *const ErrorType
All the structs are opaque and they get accessors using the previous pattern

Is there any way to auto-generate these?

I am coming with 0 expertise to this topic, but at first glance it would seem quite tedious and error-prone having to implement all of this manually and even worse having to keep things in sync over time...
