C-call-graph-producer

通过cflow，tree2dotx，graphviz创建c语言文件的函数调用关系图，并集成为一条命令

tree2dotx.sh 转自CSDN-cflow——C语言函数调用关系生成器

等待添加功能：检查文件是否存在、不显示某一函数/系统函数、自动识别类型

使用方法

带星号(*)的是默认选项

cgraph [-a <NUM>] [-d <NUM>] [-e <NUM>] [-r <NUM>] [-f <file1 file2...>] [-m <MODE>] [-T <TYPE>] [-o <NAME>] [-h]

-a [NUM] :

NUM	function
0	Produce graphs only for main function(*)
1	Produce graphs for all global functions
2	Produce graphs for all functions

-d [NUM] :

       Set the depth at which the flow graph is cut of

-e [NUM] :

NUM	function
0	Disable display file name where the function is located
1	Enable display file name where the function is located(*)

-r [NUM] :

NUM	function
0	Disable output in the order in which the functions appear
1	Enable output in the order in which the functions appear(*)

-f [filename]:

       The files you want to produce call graph, default: all .c file in the folder
       use "filename1 filename2" to set multiple files as input

-m [MODE] :

MODE	description
dot	Digraph (layering)(*)
neato	Based on spring-model
twopi	Radial layout
circo	Circle layout
fdp	Undigraph
patchwork	Square tree

-T [TYPE] :

TYPE	function
jpg	Output .jpg file(*)
png	Output .png file
gif	Output .gif file
svg	Output .svg file

-o [FILENAME] :

       output file name, default: a.out

-h :

使用示例

创建一个包含 a.c和b.c中所有函数的，不按函数出现顺序输出的，显示函数所在文件名的函数调用图，输出为test.svg

cgraph -a 2 -r 0 -T svg -o test.svg
