Re: FLI Foreign Callable with string argument

I'm away from the computer ATM, but I'm pretty sure it'd be something like this:

(define-foreign-callable (my-function "my_function" :void)

((str (:reference :ef-mb-string)))

(print str))

If the :reference doesn't work then just use (:pointer :char) and convert in the body:

(let ((s (convert-from-foreign-string str)))

(print s))

Is that what you needed?

Hello All,

I’m having some trouble figuring out how to define a foreign callable that takes a string argument. The C prototype is below. Any help would be greatly appreciated.

void callback(void (*func)(char *));

Thanks,

Gerry
