Arguments: forms &key print
This function is obsolete and maintained for backwards compatibility only. There is no real equivalent in the redesigned interface. defforeign has been replaced by the macro def-foreign-call. All new code should use that macro, calling it repeatedly if a number of foreign functions must be defined.
This function allows you to define many foreign functions at once. It may be more convenient but it is no faster than calling defforeign many times. This function returns the number of unsuccessful definitions so a returned value of 0 means that all definitions were successful. The following definition is functionally equivalent to the definition of defforeign-list.
(defun simple-defforeign-list (list-of-arg-lists) (let ((errors 0)) (dolist (arg-list list-of-arg-lists errors) (unless (apply #'ff:defforeign arg-list) (incf errors)))))
Each arg-list argument must be a list of the arguments that would be passed to defforeign. Note that the individual lists are processed in an apply form and thus the elements in the individual lists are not evaluated as they would be if the same values were passed directly to defforeign. For example, if you want elements of the lists evaluated, you must backquote the entire list of arg-lists and put commas before those elements which require evaluation.
