Subject: Unsigned int ?!
Date: 16 Jun 2000 11:57:15 +0200 [thread overview]
Message-ID: <87pupigd8k.fsf@beepbeep.dev33.cvf> (raw)
I would like to get the "caml unsigned int value" of an "unsigned int C
value". Is there a way to do this ??
I do the following, and it fails ...
---toto_stub.c---
value toto(void)
{
return Val_int(get());
}
------------
---toto.mli---
val toto : unit -> int ;;
------------
---toto.ml---
external toto : unit -> int = "toto";;
-------------
---test.c---
<<some stuff>>
printf("%d\n", toto()); /* unsigned int: --> 3 */
<<some stuff>>
-----------
---test.ml---
let t = toto () ;;
val t : int = -924646501 /* uh ?? */
-------------
