[Openmcl-devel] A (stupid?) question

I was looking at the documentation for the OpenMCL foreign function
interface and was intrigued by the defcallback macro. I understand (I
think) what is does, but I am confused as to how one takes advantage of
this functionality. Specifially, how does one write C code that takes
advantage of the callback defined by defcallback. Say, (for a really
silly example) I wanted to do the following:
(defcallback exchange (:single-float dollars :single-float rate
(* dollars rate))
How would I then write a C program to call that function?
Or am I completely missing the point?
Thanks for tolerating my silliness.
