[Chicken-users] do I use define-foreign-variable correctly ?

[minh thu]

#>!
#include <X.h>
#include <keysym.h>
<#

(define-foreign-variable c-escape-key int "XK_Escape")
(define escape-key c-escape-key)

Do I need to have those two lines too be able to use escape-key as a
Scheme symbol for the C #defined XK_Escape value ?

Thanks,
thu
