From Rust to C and Back Again: an introduction to "foreign functions"

An introduction to "foreign functions" (FFI) in Rust and C. This talk goes through calling C standard library functions, using the cc crate to build and link our own C code, and using the bindgen crate to generate bindings from a header file. These are advanced topics, but some beginners run into these topics early on, so hopefully this talk is accessible to anyone who knows some Rust and maybe a little bit of C.
