[Chicken-users] xlib egg

[Adam C. Emerson]

I'm experimenting with the xlib egg, and I'm having some trouble with
the xnextevent procedure.  As far as I can ascertain, I need to pass
in a C pointer.  So I tried this:

  (let* ((e (make-vector 1))
         (l (make-locative e 0)))
    (xnextevent dpy l)
    (vector-ref e 0))

However, what I get from my vector-ref is an integer.  This doesn't
seem to work, as procedures such as xevent-type expect a pointer.  Is
there some trick that I'm not getting?
