这一职能是否与它的论点相同?
原标题:Does this function return the same pointer as its argument?

我已在C处写了这一职务:

void *PWNRetain(void *object) {
  PWNObject *obj = (PWNObject *)object; // <-- looks stupid, I know :)
  obj->retainCount++;
  return obj;
}

重要的是,这将回到与其论点相同的点。 <代码>obj等于object,还是我犯了另一点错误? 感谢:

最佳回答

是的,这将回到C的同一点。 事实上,你不需要在第二行中明确表述,因为C允许从<代码>中删除*到其他点类型。

问题回答

典型的情况是,人们将使用预先宣布其结构,以促成类型安全,但你的法典将发挥预期的作用,实际上将返回同一点。
