Subject: C-Interface: CAMLreturn and failwith
Date: Fri, 20 Jan 2006 13:18:37 +0100	[thread overview]
Message-ID: <26EB47FDD566A7469FC862DAF373792F07D737@kaiserslautern1.lmsintl.com> (raw)

Hi,

a question related to CAMLreturn and failwith in C-Stubcode:

Is this code correct:

#include <fail.h>
...

CAMLprim value prim( value unit ) 
{
   CAMLparam0();
   CAMLlocal( result );
   int error;
   /* allocate result, error has an errorcode */
   if( error ) failwith( "error");
   else CAMLreturn( result );
}

or should it be

CAMLprim value prim( value unit ) 
{
   CAMLparam0();
   CAMLlocal( result );
   int error;
   /* allocate result, error has an errorcode */
   if( error ) {
      caml_local_roots = caml__frame;
      failwith( "error");
   }
   else CAMLreturn( result );
} 

Thanks,
