VeriFFI is a verified Foreign Function Interface (FFI) for Coq (Gallina) programs that call, and are called by, C programs. The operational connection is by compiling Gallina programs through C using the CertiCoq compiler. The specification/verification connection is by using the Verified Software Toolchain (Verifiable C) to specify library functions written in C that are callable by CertiCoq-compiled programs, and vice versa. The goal is to have a fully foundational soundness proof for this connection. This is still a work in progress.
