Alien callback support +;;;; +;;;; This is basically the implementation posted by Helmut Eller, +;;;; posted to cmucl-imp on 04/13/2003. It has been modified to live +;;;; in the ALIEN package and to fit the same style as the ALIEN +;;;; package. + +;;; This package provides a mechanism for defining callbacks: lisp +;;; functions which can be called from foreign code. The user +;;; interface consists of the macros DEFCALLBACK and CALLBACK. (See +;;; the doc-strings for details.) +;;; +;;; Below are two examples. The first example defines a callback FOO +;;; and calls it with alien-funcall. The second illustrates the use +;;; of the libc qsort function. +;;; +;;; The implementation generates a piece machine code -- a +;;; "trampoline" -- for each callback function. A pointer to this +;;; trampoline can then be passed to foreign code. The trampoline is +;;; allocated with malloc and is not moved by the GC. +;;; +;;; When called, the trampoline passes a pointer to the arguments +;;; (essentially the stack pointer) together with an index to +;;; CALL-CALLBACK. CALL-CALLBACK uses the index to find the +;;; corresponding lisp function and calls this function with the +;;; argument pointer. The lisp function uses the pointer to copy the +;;; arguments from the stack to local variables. On return, the lisp +;;; function stores the result into the location given by the argument +;;; pointer, and the trampoline code copies the return value from +;;; there into the right return register. +;;; +;;; The address of CALL-CALLBACK is used in every trampoline and must +;;; not be moved by the gc. It is therefore necessary to either +;;; include this package into the image (core) or to purify before +;;; creating any trampolines (or to invent some other trick). +;;; +;;; Examples: + +#|| +;;; Example 1: + +(alien:def-callback foo (c-call:int (arg1 c-call:int) (arg2 c-call:int)) + (format t "~&foo: ~S, ~S~%" arg1 arg2) + (+ arg1 arg2)) + +(alien:alien-funcall (alien:sap-alien (alien:callback foo) + (function c-call:int c-call:int c-call:int)) + 555 444444) + +;;; Example 2: + +(alien:def-alien-routine qsort c-call:void + (base (* t)) + (nmemb c-call:int) + (size c-call:int) + (compar (* (function c-call:int (* t) (* t))))) + +(alien:def-callback my< (c-call:int (arg1 (* c-call:double)) + (arg2 (* c-call:double))) + (let ((a1 (alien:deref arg1)) + (a2 (alien:deref arg2))) + (cond ((= a1 a2) 0) + ((< a1 a2) -1) + (t +1)))) + +(let ((a (make-array 10 :element-type 'double-float + :initial-contents '(0.1d0 0.5d0 0.2d0 1.2d0 1.5d0 + 2.5d0 0.0d0 0.1d0 0.2d0 0.3d0)))) + (print a) + (qsort (sys:vector-sap a) + (length a) + (alien:alien-size c-call:double :bytes) + (alien:callback my<)) + (print a)) + +||# + +(defstruct (callback + (:constructor make-callback (trampoline lisp-fn function-type))) + "A callback consists of a piece assembly code -- the trampoline -- +and a lisp function.
