【转】cscope 用法

由于公司的代码有点大，光用grep个人感觉太慢了，所以就到网上去找了找cscope的用法。感觉也挺实用的。
以下命令，用来生成cscope的索引文件，
find . -name "*.h" -o -name "*.c"  > cscope.files
cscope -bkq -i cscope.files
然后就可以在vim里使用了，加粗的那几个，用的比较多点。
    find  : Query cscope.  All cscope query options are available
            except option #5 ("Change this grep pattern").
        USAGE   :cs find {querytype} {name}
                0 or s: Find this C symbol
                1 or g: Find this definition
                2 or d: Find functions called by this function
                3 or c: Find functions calling this function
                4 or t: Find this text string
                6 or e: Find this egrep pattern
                7 or f: Find this file
                8 or i: Find files #including this file
