How can I find those more professional sites? I'd need some, as it's sometimes hard to find info on OS API, as "it's bad practice to not use Johnny's Janky and Bloated Everything Library (JJBEL), that still handles XInput controllers through the DirectInput API, but it also has other extras". I've had issues with RawInput under Windows (with that, in theory, I can use Xbox One/Series controllers to their fullest potential), and all I get is either SEO-ridden advertisements for existing libraries (which wouldn't be a problem if they didn't have massive problems), or tutorials for said libraries. Since I'm working with D, I have to interface to C calls, which wouldn't be a problem if they were documented properly and in an accessible way.

My own D native and less bloated SDL replacement's (iota) development got halted for getting null for device pointers no matter what, and with no proper instructions on how to resolve it.
