Hi,

I'm trying to integrate a C program with CLISP.

Here's my C function:
int create_window(int x_pos, int y_pos) 
{ ... }

Here's my Lisp interface (logo-interface.lisp):
(ffi:def-call-out create-window 
    (:name "create_window") 
    (:language :stdc) 
    (:arguments (x_pos int) (y_pos int)) 
    (:return-type int))

But when I execute: clisp -c logo-interface.lisp

I get:
Compiling file /usr/home/rjs/work/logo/logo-interface.lisp ...
*** - Incomplete FFI type INT is not allowed here.

Any help will be greatly appreciated.

Thanks,
Russell

Here, you want FFI:INT. Or else use the FFI package in the present
package so you can refer to these symbols by their unqualified names.

Thank-you! That fixed it.
