Hi!
There's a version of clisp which can deal with foreign function, inside the
distribution
of this version, you'll be able to find some explanations, here a short sample:

File foreign.txt of clisp_with_ffi.tgz
        
                         The Foreign Function Call Facility
                         ==================================

        A foreign function description is written as a Lisp file,
        and when compiled it produces a .c file which is then compiled
        by the C compiler and may be linked together with lisp.a.

        All symbols relating to the foreign function interface are exported from
        the package FFI. To use them, (USE-PACKAGE "FFI").

        Special FFI forms may appear anywhere in the Lisp file.
