The type you want is:
let sp = pointer_type i8_type in
var_arg_function_type sp [| sp; sp |]

[LLVMdev] How to declare and use sprintf
So my Fib program is segfaulting and I'm not sure why. I think it might be
because my declaration and use of sprintf is wrong.
I notice llvm-gcc produces declarations containing "..." like:
declare int %printf(sbyte*, ...)
but I'm not sure how to do this so I've used:
let sprintf =
declare_function "sprintf"

Awesome stuff. Here is my most elegant Fibonacci example in OCaml so far:
open Llvm
let ( |> ) x f = f x
let int n = const_int i32_type n
let return b x = build_ret x b |> ignore
let build_fib m =
let ty = function_type i32_type [| i32_type |] in
let fibf = define_...

[LLVMdev] Fibonacci example in OCaml
Here's my translation of the Fibonacci example into OCaml:
open Printf
open Llvm
let build_fib m =
let fibf =
define_function "fib" (function_type i32_type [| i32_type |]) m in
let bb = builder_at_end (entry_block fibf) in
let one = const_int i32_type 1 and two = const_int i32_type 2 in
let argx = param fibf 0 in
set_value_name "AnArg" argx;
