For just this, you could do :
let sprint msg =
print_string "BEGIN: ";
printf msg;;
But generally speaking, you need kprintf from the
Not yet, it need kprintf that is in the development version of ocaml:
# Printf.kprintf;;
- : (string -> string) -> ('a, unit, string) format -> 'a = <fun>
so it would be something as :
let sprint msg =
let aux res =
print_endline ("BEGIN: " ^ res);
res in
kprintf res msg;;
