I'm not sure that I fully understand your question, but:
You can't refer to lisp functions (or to symbols that name them, or to any
other kinds of lisp objects) from foreign code in OpenMCL.
You can (using OBJC:DEFMETHOD) define ObjC-callable methods that are
implemented in lisp, and pass foreign arguments to and return foreign
results from those methods. There are lots of examples of this
in the ccl:examples; directory.
