Not sure about UE but I’ve worked on other engines and usually you just have an interface that abstracts platform APIs and each platform implements the same int

Not sure about UE but I’ve worked on other engines and usually you just have an interface that abstracts platform APIs and each platform implements the same interface The implementations get compiled in based on whatever platform you’re compiling for using a bunch of #ifdef statements In that case it’s just a matter of not including certain .h/.cpp files
