1、生成动态链接库
[[email protected] c]# more head.c #include <stdio.h> #include <stdlib.h> typedef struct _point{ int x; int y; }Point; Point * InitPoint(int x,int y) { Point *p = (Point *)malloc(sizeof(Point)); p->x = x; p->y = y; return p; } Point * Incre(Point * p) { p->x = p->x + 1; p->y = p->y + 1; return p; } gcc -fPIC -shared -o libhead.so ./head.c
python调用
[[email protected] ice_test_m c]# more test.py #!/usr/bin/env python2.7 #-*- coding:utf-8 -*- from ctypes import * class Point(Structure): _fields_ = [("x",c_int),("y",c_int)] if __name__ == ‘__main__‘: ddl = CDLL("./libhead.so") ddl.InitPoint.restype = POINTER(Point) p = ddl.InitPoint(5,6); print p.contents.x print p.contents.y [[email protected] ice_test_m c]# ./test.py 5 6
python调用c代码2
