How do I make functions "known" to C land that are purely defined as callbacks in Lisp land?
You can't do that directly. Lisp callbacks must be passed to the C code as function pointers. You could write a C wrapper that calls the callback through a global variable and have the Lisp-side store the address of the callback in that variable.
Hmm - thanks! I hoped for a far more elegant solution ... Well, it's C after all ... ;-)
