Unifex

Unifex is a tool for generating interfaces between native C code and Elixir, that:

• provides intuitive and concise tools for defining native interfaces,
• generates all the boilerplate for you,
• provides useful abstractions over binaries and state,
• makes native code independent from erl_nif or ei library, so the same code is usable either with NIFs or CNodes.

API documentation is available at HexDocs.

Unifex uses Bundlex to compile and load the native code. See there for supported platforms & details.

This tool is maintained by the Membrane Framework team.

This version supports bugged version of functions returning nil, as well as fixed ones. This functionality should be removed in version 2.0.0 For more info see: Issue

defmodule MyApp.Mixfile do
  use Mix.Project

  def project do
    [
      app: :my_app,
      compilers: [:unifex, :bundlex] ++ Mix.compilers, # add unifex and bundlex to compilers
      ...,
      deps: deps()
   ]
  end

      {:unifex, "~> 1.2"}
