libffi-sys-rs: Low-level Rust bindings for libffi

Build Status Crates.io License: MIT License: Apache 2.0

The C libffi library provides two main facilities: assembling calls to functions dynamically, and creating closures that can be called as ordinary C functions. This is an undocumented wrapper, generated by bindgen, intended as the basis for higher-level bindings, but you can see the C libffi documentation.

See the libffi crate for a higher-level API.

Usage

It’s on crates.io, but before you build it, make sure you have the dependencies installed first:

  • An up-to-date version of C libffi Version 3.2.1 is known to work. Earlier versions, such as the versions that come with Mac OS and Fedora, are known not to; neither will the version installed by Homebrew (3.0.13).

  • pkg-config, which you probably already have if you’re on Linux. For Mac users, the version installed by Homebrew is up to date. (I don’t know how this works on Windows; contact me if you’d like to help figure it out.)

Then add

[dependencies]
libffi-sys = "0.3"

to your Cargo.toml and

extern crate libffi;

to your crate root.
