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
