Hi all,
I'm writing a C stub function to allow the calling of a C library
function from ocaml. The return from the stub is a tuple and I'm
doing this:
/* Package up the result as a tuple. */
v_response = caml_alloc_tuple (3) ;
Store_field (v_response, 0, Val_int (width)) ;
Store_field (v_response, 1, Val_int (height)) ;
Store_field (v_response, 2, caml_copy_string (code)) ;
CAMLreturn (v_response) ;
The above works now, but didn't work when I was using
caml_copy_nativeint() instead of Val_int() and I'd like to know
why. I found it especially confusing because caml_copy_string()
worked and was obvioulsy the right thing to do.
Cheers,
Erik
