我有一个 python 文件,我想从中调用一个 dll 中的函数。
该函数的原型是:
typedef double real_T;
extern real_T __declspec(dllexport) RectIntersect(const real_T rect1[8], const real_T rect2[8]);
蟒蛇代码:
import math;
import ctypes;
from ctypes import *
import numpy;
# this module shall always be executed directly
if __name__ == '__main__':
print "Program started !";
rect = ctypes.c_double * 8;
rect1 = rect(1.1, 2.45, 3, 4, 5, 6, 7, 8);
rect2 = rect(1.6, 3.45, 3.1, 4.1, 5.1, 6.1, 7.1, 8.1);
# Load DLL into memory.
hllDll = ctypes.WinDLL ("IntersectDLL.dll");
hllDll.RectIntersect.argtypes =[ctypes.c_double * 8, ctypes.c_double * 8];
hllDll.RectIntersect (rect1, rect2);
我得到错误:
Traceback (most recent call last):
File "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\Python Tools for Visual Studio\2.0\visualstudio_py_util.py", line 70, in exec_file

hllDll.RectIntersect (rect1, rect2);
ValueError: Procedure probably called with too many arguments (8 bytes in excess)
请帮忙 :(。 ....
