您需要修改 c-offsets-alist 中的$ c> access-label 缩进。
我建议您使用自己的 c-offsets-alist 制作新的样式，并添加如下一行：

You need to modify the access-label indentation in your c-offsets-alist. I recommend you make a new 'style' with its own c-offsets-alist and add a line like:

（访问标签。+）

如果要从 bsd 样式，您可以执行以下操作：

If you want to derive from bsd style, you can do something like this:

(c-add-style "modified-bsd"
'("bsd"
  (c-basic-offset . 2)
  ;;...MORE MODS...
  (c-offsets-alist
   (access-label . +))))`

另外，我怎么找到要修改的偏移量？转到相关的代码行，然后按
C-c C-s 显示CC模式的语法分析。另外，请务必检查 c-offsets-alist 的帮助。

Also, how did I find the offset to modify? Go to the relevant line of code and press C-cC-s to show the syntactic analysis of CC-mode. Also be sure to check the help for c-offsets-alist.
