How to use cscope?
提问by narayanpatra
I am using cscope to get familiar with all the keywords used in socket programming. I went to the directory with c files. I used cscope. and then I searched for AF_INET. I got this :
我正在使用 cscope 来熟悉套接字编程中使用的所有关键字。我去了有c文件的目录。我用过cscope。然后我搜索了 AF_INET。我懂了 ：
#define AF_FILE PF_FILE
#define AF_INET PF_INET
#define AF_AX25 PF_AX25
This was a full page. I only published part of it. Now I want to know from where this PF_INET is coming? what command I should use. I have seen a guy to double click on PF_INEt and using some command to find it. I don't know what the command is? Kindly help me in this.
这是一个完整的页面。我只发表了一部分。现在我想知道这个 PF_INET 是从哪里来的？我应该使用什么命令。我见过有人双击 PF_INEt 并使用一些命令来找到它。不知道是什么命令？请帮助我。
The second thing is when i quit the page with :q command. I come to this page :
第二件事是当我使用 :q 命令退出页面时。我来到这个页面：
Global definition: AF_INET
File Line
0 socket.h 119 #define AF_INET PF_INET
Find this C symbol:
Find this global definition:
Find functions called by this function:

here the cursor is blinking at 0. If I want to search again something, how I will do? How to navigate from here. I tried to google it but unable to understand anything from the tutoials. Please help me in this regard as I am complete noob to linux operating system and c programming. Thanks in advance.
此处光标在 0 处闪烁。如果我想再次搜索某些内容，我将怎么做？如何从这里导航。我试图用谷歌搜索它，但无法理解教程中的任何内容。请在这方面帮助我，因为我对 linux 操作系统和 c 编程完全是菜鸟。提前致谢。

I agree that cscope documentation is not very clear.
我同意 cscope 文档不是很清楚。
Use tab to move to the interactive part. Type your symbol name in “find this C symbol” or “Find this egrep pattern” and validate pressing RETURN.
使用 Tab 键移动到交互部分。在“查找此 C 符号”或“查找此 egrep 模式”中键入您的符号名称，然后按 RETURN 确认。
If you want to call it from vim, type :help if_cscop.txt; hoping it helps!
如果你想从 vim 调用它，输入:help if_cscop.txt; 希望有帮助！
:cscope add your_cscope_database
:cscope find s [your_symbol]
This will make a new quickfix list. use :cnand :cpto navigate, :cnfand :cpfto navigate from file to file in the results, and :colderand :cnewerto restore previous quickfix lists.
这将创建一个新的快速修复列表。使用:cn和:cp浏览，:cnf并:cpf从文件中的结果定位到文件，:colder并:cnewer恢复以前的quickfix列表。

To exit from cscope interactive prompt, type Ctrl-d. If you just want to rebuild cscope's database, and not invoke cscope's interactive prompt, pass it the -b option. I usually invoke cscope as cscope -bcqR.
要退出 cscope 交互式提示，请键入Ctrl-d。如果您只想重建 cscope 的数据库，而不是调用 cscope 的交互式提示，请将 -b 选项传递给它。我通常将 cscope 作为cscope -bcqR.
As for jumping around in vim using cscope, it really depends on your vim config.
至于使用 cscope 在 vim 中跳转，这实际上取决于您的 vim 配置。
Most probably, jump to tag (Ctrl-]) will use cscope first, then ctags (see :help cstand :help csto). Use Ctrl-Tto go back.
最有可能的是，跳转到 tag ( Ctrl-]) 将首先使用 cscope，然后是 ctags（参见:help cst和:help csto）。用于Ctrl-T返回。
There are some useful mappings for cscope that you can find by typing :help cscope-suggestionsin vim. After adding those mappings to your .vimrc, you will be able to jump to symbols using Ctrl-_ s, the calling function using Ctrl-_ c, etc...
通过:help cscope-suggestions在 vim 中键入，您可以找到一些有用的 cscope 映射。将这些映射添加到您的 .vimrc 后，您将能够使用 跳转到符号Ctrl-_ s，使用Ctrl-_ c等调用函数...
You can access vim's cscope documentation by typing :help cscope.
您可以通过键入来访问 vim 的 cscope 文档:help cscope。

I mostly use the following. These are very basic to understand the cscope.
我主要使用以下内容。这些是理解 cscope 的基础。
- "cscope -R" Then you get options.
- Press down arrow. Then you will move to your required option. Type whatever you want at the respective option.
- From the search result. Use arrows(Up and down) then Press "enter key" to see the detailed file.
- ":q" to exit from the file.
- Press "Tab key" to come to the cscope options.
- "ctrl + d" to exit from the cscope.
- "cscope -R" 然后你会得到选项。
- 按向下箭头。然后，您将转到所需的选项。在相应的选项中输入您想要的任何内容。
- 从搜索结果来看。使用箭头（向上和向下）然后按“输入键”查看详细文件。
- ":q" 退出文件。
- 按“Tab 键”进入 cscope 选项。
- “ctrl + d”退出cscope。
