Foreign Function Interface

The foreign function interface (FFI) lets Rux call functions defined outside the language — typically in C / C++ libraries — and exchange data with them. Each part of the FFI has a dedicated chapter:

Topic	Description
extern Declarations	Declaring functions defined outside Rux
Import Attribute	Linking declarations to a dynamic library

Pointers are central to passing memory across the boundary — see Pointers and extern.
