Python c_ulong类型在macOS上为64位
[英]Python c_ulong type is 64 bits on macOS
问题描述
It seems that on macOS Python's c_ulong type is 64 bits, instead of the 32 bits that it would be on Windows. 
在macOS上，Python的c_ulong类型似乎是64位，而不是Windows上的32位。 From what I've found in my google search, based on this post: Is Python's ctypes.c_long 64 bit on 64 bit systems? 根据我在Google搜索中发现的信息，基于这篇文章： Python的ctypes.c_long在64位系统上是否为64位？
It looks like it's because of macOS's memory model. 看起来是因为macOS的内存模型。 Is there any fix for this? 有没有解决办法？

Just like if you are writing C, if you know that you specifically need a 32 bit unsigned integer, you shouldn't use c_ulong but instead ctypes.c_uint32 . 就像您正在编写C一样，如果您知道特别需要32位无符号整数，则不应使用c_ulong ，而应使用ctypes.c_uint32 。 This way you can ensure it will be 32 bits no matter the platform you are on. 这样，无论使用什么平台，都可以确保32位。
