swig 教學文

閱讀 https://www.swig.org/ 這個網站，寫一篇教學文，教導如何使用 swig 這個工具來將 C++ library 包裝成 Python library。 教學要從簡單到進階，每一階段都要給出範例與解說。

範例建立一個 C++ 的 class，分3階段將這個class複雜化，並用 swig 建立 Python library。 作業系統: Windows 11 編譯環境: Visual Studio 2022 Python 版本： 3.12

Create global mutex

Use ctypes and Win32Api CreateMutex to create a global mutex here. Use class to wrap it. This mutex shoid has these features:

1. When user instantiate this class, use Win32api OpenMutex to try to open this global mutex, because this mutex mybe alreday created in another process.
2. if OpenMutex failed, use CreateMutex to create the global mutex.
3. this class should provide lock and unlock function, use WaitForSingleObject and ReleaseMutex to implement it.
4. And, very important, class should has release function of mutex.
