How about this? In fsbv.lisp

      ;;; Combine structures by value with a string argument
      (deftest fsbv.7
      (stringlenpair "abc" '(1 . 2))
      (3 . 6))


      and in libfsbv.c

      DLLEXPORT
       struct struct_pair stringlenpair (char * string, struct struct_pair dp)
       {
         struct struct_pair ret;
         ret.a = strlen(string)*dp.a;
         ret.b = strlen(string)*dp.b;
         return ret;
       }

Can you run this and see if it works? I've never figured out how to run tests.

Thanks,
Liam
