I have an ECL interpreter embedded in a C application, linked with
-lecl. I have a global string
char name[32];
strcpy(name, "hello");
The C function GetName returns the address of name[],
int GetName()
{ return (int)name); }
I use a c-inline to call GetName from Lisp to return the address.
(defun get-current-address ()
(ffi:c-inline () () :int "GetName()" :one-liner t))
So, I get the address in Lisp,
(setq ptraddr (get-current-address))
and create a pointer
(setq ptr (uffi:make-pointer ptraddr :void))
or perhaps I should use '(* :char) for the type.
This seems to work fine. But I want to dereference ptr to display the
string in Lisp. What am I missing? Can you show an example?
