示例1:
// Cons lists
static Box *op_cons(ListBox *args)
{
ListBox *ret = 0;
for (ListBox *b = args; !b->isEmpty(); b = b->tail())
{
Box *box = b->head();
if (!box->isListBox())
{
VSLLib::eval_error("invalid argument -- argument is list");
if (ret)
ret->unlink();
return 0;
}
if (!((ListBox *)box)->isEmpty())
{
// Create list to append
// If box is last arg, a link suffices
ListBox *box2;
if (b->tail()->isEmpty())
box2 = (ListBox *)box->link();
else
box2 = (ListBox *)box->dup();
// Append list:
// If box is first arg, copy box
if (ret == 0)
ret = box2;
else
{
ret->cons(box2);
box2->unlink();
}
}
}
// No args? return []
if (ret == 0)
ret = new ListBox;
return ret;
