VC ++ Watch窗口中{???}是什么意思？ [英] What does the {???} mean in the VC++ Watch window?

问题描述

我正在使用Visual Studio 2013调试C项目。 {???} 在下面的 Watch 窗口？

I am debugging a C project with Visual Studio 2013. What does the {???} mean in the below Watch window?

我想有一定是错了，我搜了一下。但是没有运气。

I guess there must be something wrong and I searched a bit. But no luck.

推荐答案

Igor的建议是正确的，这是这个问题的样本。

Igor’s suggestion is correct, this is the sample for this issue.

如果我禁用行代码currnode-> nextnode = NULL;，它将显示与您相同的结果。

If I disable the line code "currnode->nextnode = NULL;", it will show the same result as yours.

但是如果我启用它，它将显示这个屏幕截图的NULL值，所以它将与null值指针。

But if I enable it, it would show the NULL value like this screen shot, so it would be related to null value of the pointer.
