The Common Foreign Function Interface for Common Lisp
CFFI, the Common Foreign Function Interface, purports to be a portable foreign
function interface for Common Lisp. The CFFI library is composed of a
Lisp-implementation-specific backend in the CFFI-SYS package, and a portable
frontend in the CFFI package.

The CFFI-SYS backend package defines a low-level interface to the native FFI
support in the Lisp implementation. It offers operators for allocating and
dereferencing foreign memory, calling foreign functions, and loading shared
libraries. The CFFI frontend provides a declarative interface for defining
foreign functions, structures, typedefs, enumerated types. It is implemented
in portable ANSI CL making use of the low-level operators exported by
CFFI-SYS.

A UFFI compatibility layer is also being developed.
