Use of csflood

In vim, cscope is used to quickly locate the function definition and find the function prototype, which is very convenient.

On my fedora8 machine, cs.pdf has been installed by default.Program.

I am not very familiar with cssag. Many "advanced" functions will be available for further exploration. Here we will first write down the simple use of csflood in VIM so thatSource codeMedium:
1. quickly switch to the function definition.
2. function declaration.
3. query the usage of a function.

First, let Vim support csflood ~ /. Add the following to vimrc:
"Set cscopequickfix = s-, C-, D-, I-, T-, e -"

Second, in the sourceCodeDirectory to generate information about CSWs.
The libpcap code is used as an example.
# Cd/usr/code/Libpcap
# Cs1_rbq

# Import the generated cscope file to VIM
#: CS Add/usr/code/Libpcap/cscope. Out/usr/code/Libpcap/

Next we can perform the actual drill operation in vim.

1. move the cursor to a function. use Ctrl +] to jump to the function definition.

2. Find the Declaration and definition of a function:
: CS find G strcpy

3. If multiple function declarations and definitions are found, you can use the quickfix window to switch between them:
: CW

In addition, more functions can be used to find related help. The following describes some Cs find techniques that can be used.

cscope main function is achieved through the same sub-command "find"
"cscope find" Usage:
CS find c | d | E | f | G | I | S | T name

0 or S	search for the c symbol (annotations can be skipped)
1 or G	search for this definition
2 or D	Find the function called by this function
3 or C	Find the function that calls this function
4 or T	search for this string
6 or E	find the current egrep mode
7 or F	search for this file
8 or I	Search for files containing this file

it is really annoying to enter a long string of commands for each search. Some shortcut keys are recommended in the cssag help manual. Below are a group of them, I also use it. Add the following content ~ /. Vimrc and restart VIM:

NMAP S: CS find S = expand (" ") NMAP G: CS find G = expand (" ") NMAP C: CS find C = expand (" ") NMAP T: CS find t = expand (" ") NMAP E: CS find e = expand (" ") NMAP F: CS find F = expand (" ") NMAP I: CS find I ^ =expand (" ") $ NMAP D: CS find d = expand (" ")

when the cursor stops on a word you want to search for, pressing G is to find the definition of the object. The same applies to other words.
one trick is to press this key combination. If you press , You need to press the next key immediately, otherwise, the screen will return to the nomal state as soon as it is flashed.
the G method is to press "Ctrl + Shift +-" first -", then press "G"
