I'm not aware that most CL implementations support a
pointer-to-function abstraction. Looking at Allegro's documentation, I
see that it does not. I'd probably store such a pointer as a
:pointer-void.

However, if you know a way to better present such pointers in
AllegroCL, Lispworks, CMUCL, and SBCL (the primary supported
platforms), I could add that as a primitive type to UFFI.=20

You mention perhaps not reading the manual, you may like better
reviewing the test suite files in tests/*.lisp which contain many
examples of using UFFI.
