我需要对 VMware 的 VIX API 进行编程。它是一个用 C 函数编写的 dll... 我想用 Python 调用这些函数，将它们编程为使用 ctypes，并且我不明白 Python 网页上 ctypes 的文档... 有人能提供一些有关如何做到这一点的示例吗？ 谢谢，

一段时间以来，我一直想做这样的事情。我下载了 VIX API 工具包，并提取了包含所有 VIX API 函数原型的 vix.h 文件。然后，我编写了一个简短的 pyparsing 解析器来提取类型定义和函数声明，并将其转换为 ctypes 定义。使用这些定义，您将能够从 VIX dll 调用 VIX 方法（不需要 lib，ctypes 只使用 dll）。 将此代码提取到合适命名的 Python 模块（例如，vixlib.py），然后将此模块导入任何 Python 脚本以使用 VIX：
from ctypes import *
# if on Windows, may need to change following to use WinDLL instead of CDLL
vix = CDLL('vix.dll')
