GTK_RETLOC_INT usage problem inside a marshaller.

["DC A" <adc4444@xxxxxxxxxxx>]

I know it is deprecated but I still want to know the answer to
this problem. In this example why GTK_RETLOC_INT() was used?
Doesn't setting pointer address values arbitrarily create
a problem(GtkArg's gint int_data(inside union d) can be
anything)? Then why use it? Can anyone kindly explain the
inner meanings?

typedef gint (*GtkSignal_INT__POINTER) (GtkObject * object,
                                        gpointer arg1,
                                        gpointer user_data);
void
gtk_marshal_INT__POINTER (GtkObject * object,
                          GtkSignalFunc func,
                          gpointer func_data,
                          GtkArg * args)
{
  GtkSignal_INT__POINTER rfunc;
  gint *return_val;
  return_val = GTK_RETLOC_INT (args[1]);
  rfunc = (GtkSignal_INT__POINTER) func;
  *return_val = (*rfunc) (object,
                          GTK_VALUE_POINTER (args[0]),
                          func_data);
}



Thanks.
