You could create the type object once at program startup and use it many times. (define foo-type (list int int (make-list 2000000 int))) (define make-foo (pointer->procedure foo-type (dynamic-func "make_foo" libfoo) (list int int))) (parse-c-struct (make-foo 4 11) foo-type) (parse-c-struct (make-foo 12 5) foo-type) (parse-c-struct (make-foo 8 91) foo-type) ...
