python调用c代码

1、 C 代码
1.1 test.c

#include<stdio.h> #include<stdlib.h> #include"test.h" int hello() {  printf("hello word 666\n"); return 255;  } 

1.2 test.h

#include<stdio.h> #include<stdlib.h> int hello(); 

1.3 调试用的main.cpp

#include"test.h" int main() {  hello(); hello();  } 

2、将test.c 里面的函数封成.so

gcc -fPIC -shared test.c -o libtest.so 

3、python 调库

import os from ctypes import * from ctypes import CDLL,c_int,c_void_p so_path= os.getcwd()+'/libtest.so' print(so_path) c_functin=CDLL(so_path) hello=c_functin.hello hello() hello() hello() 

4、目录结构

5、运行结果
