ctypes python3,如何在python3中使用ctypes void**指针

我想通过它的DLL连接一个光谱仪，其中一个函数被定义为UINT UAI_SpectrometerOpen(unsigned int dev, void** handle, unsigned int VID, unsigned int PID)

在文件中，dev指定了光谱仪的索引

返回分光计手柄指针

VID规定

PID提供指定PID

dev，VID，PID都是已知的，但我不知道如何设置句柄。

我现在的代码是

^{pr2}$

当我运行上面的代码时，我得到的错误是runfile('C:/Users/Steve/Documents/Python Scripts/otoDLL.py', wdir='C:/Users/Steve/Documents/Python Scripts')

Traceback (most recent call last):

File "", line 1, in

runfile('C:/Users/Steve/Documents/Python Scripts/otoDLL.py', wdir='C:/Users/Steve/Documents/Python Scripts')

File "C:UsersSteveAnaconda3libsite-packagesspyderlibwidgetsexternalshellsitecustomize.py", line 685, in runfile

execfile(filename, namespace)

File "C:UsersSteveAnaconda3libsite-packagesspyderlibwidgetsexternalshellsitecustomize.py", line 85, in execfile

exec(compile(open(filename, 'rb').read(), filename, 'exec'), namespace)

File "C:/Users/Steve/Documents/Python Scripts/otoDLL.py", line 5, in

spectrometerOpen.argtypes = (ctypes.c_uint, ctypes.POINTER(c_void_p),

NameError: name 'c_void_p' is not defined

我不熟悉ctypes和C语言，有人能帮我解决这个问题吗。

谢谢。在
