The Common Foreign Function Interface
Common Lisp C Other
Latest commit 4b706f4 Jun 22, 2016 @dkochmanski dkochmanski committed with luismbo ecl: defcallback: fix calling-convention (#93)
This is for bytecmp and the C compiler compatibility. :cdecl doesn't
work on Android, but :default works just fine. For C compiled code there
is no difference.

Build Status

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, etc. It is implemented in portable ANSI CL making use of the low-level operators exported by CFFI-SYS.

Please consult the manual for further details, including installation instructions.
