Python calls the struct and function of a C program

The C code is as follows:

#include <stdio.h>

typedef struct TESTDLL_

{

int A;

Char *b;

} Testdll;

Testdll Test (Testdll t)

{

T.A=T.A+T.A;

printf ("%d\n%s\n", t.a,t.b);

return t;

}

The Python code is as follows:

From ctypes Import *

#绝对路径

Dllpath= ' Test.dll '

Dll=cdll (DllPath)

#python内部参数赋值

A=c_int (125)

B=c_char_p (' Hello world,hello Chengdu ')

#定义结构体

Class Testdll (Structure):

_fields_=[(' A ', c_int),

(' B ', c_char_p)]

#实例化并赋值

T=testdll ()

T.a=a

T.b=b

#设置返回值类型

Dll.test.restype=testdll

#测试

T=dll.test (t)

Print T.A

Print t.b

X=raw_input (' Any key to continue ')
