RE: Fli and pointers to pointers

Thanks for the tips, but they don't seem to affect the outcome. Any other
thoughts?

You need to convert the foreign strings to lisp strings before you can call 
lisp's PRINT.

It's been a while since I've steeped myself in FLI'ism, but, in some of my
old 
code, I found this decl:

  (name (:pointer (:ef-mb-string 256)))

Further down, this field is accessed by a combination of 
convert-from-foreign-string and foreign-slot-value

(fli:convert-from-foreign-string 
     (fli:foreign-slot-value partdesc 'name))

Hope that helps.
