1 Introduction

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.

Macro: define-c-struct-wrapper CLASS-AND-TYPE SUPERS &optional SLOTS

Define a new class with CLOS slots matching those of a foreign struct type. An INITIALIZE-INSTANCE method is defined which takes a :POINTER initarg that is used to store the slots of a foreign object. This pointer is only used for initialization and it is not retained.

CLASS-AND-TYPE is either a list of the form (class-name struct-type) or a single symbol naming both. The class will inherit SUPERS. If a list of SLOTS is specified, only those slots will be defined and stored.

Define a translation method for the foreign structure type; ’method is one of :into, :from, or :to, meaning relation to foreign memory. If :into, the variable ’pointer is the foreign pointer. Note: type must be defined and loaded before this macro is expanded, and just the bare name (without :struct) should be specified.

VAR-OR-VARS is not evaluated and should be a list of the form (VAR &OPTIONAL SIZE-VAR) or just a VAR symbol. VAR is bound to a foreign buffer of size SIZE within BODY. The return value is constructed by calling FOREIGN-STRING-TO-LISP on the foreign buffer along with ARGS.

strings.lisp (file)

Macro: with-foreign-slots (VARS PTR TYPE) &body BODY

Create local symbol macros for each var in VARS to reference foreign slots in PTR of TYPE. Similar to WITH-SLOTS.
Each var can be of the form: slot-name - in which case slot-name will be bound to the value of the slot or: (:pointer slot-name) - in which case slot-name will be bound to the pointer to that slot.
