This is all very tedious, formulaic, and difficult to write, so it is typical to generate this glue automatically using tools like embind or wasm-bindgen. This streamlines the authoring process, but adds complexity to the build process that native platforms typically do not require. Furthermore, this build complexity is language-specific; Rust code will require different bindings from C++ code, and so on.
The 80286 introduced "Protected Mode" in 1982. It was not popular. The mode was difficult to use, lacked paging, and offered no way to return to real mode without a hardware reset. The 80386, arriving three years later, made protection usable -- adding paging, a flat 32-bit address space, per-page User/Supervisor control, and Virtual 8086 mode so that DOS programs could run inside a protected multitasking system. These features made possible Windows 3.0, OS/2, and early Linux.
