[Ecls-list] Tighter c/c++ integration, toplevel inline c/c++ code ???

[Seth Burleigh]

ffi:clines introduces all code into the header file and does not inline
code into the c file. Can you declare c++ class methods in header files
and in general arbitrary c/c++ code? Can  you call obfuscated lisp
functions in the header file and are functions/classes defined in the
header file automatically exported (which isn't desirable)? (i dont
know, i dont usually do this)

But besides that, i tested your code and was wondering how i access the
c code from the REPL.

> (si:system "cat foo.lisp") (FFI:CLINES " int foo(int a, int b)
{ return a+b; }
")

;;compile file foo and then ....
(load "foo.fas")


(defun test () (let ((x (ffi:c-inline (1 2) (:int :int) :int
"foo(#0,#1)" :one-liner t)))
  (print x)))
