问题描述
我是不是畏惧我找不到这个互联网上的一个简单的答案，所以也许会有一个在未来，因为这个问题！
I'm afriad I couldn't find a simple answer for this on the internet, so maybe there will be one in the future because of this question!
我使用pywiiuse，一个python包装在Windows的C wiiuse库。我已经得到了几个简单的C例子由包括dll，头和库源的目录简单的工作。
I'm using pywiiuse, a python wrapper for the C wiiuse library on windows. I've gotten several plain C examples working simply by including the dll, header, and library in the directory of the source.
不过，我不知道放在哪里DLL，以便pywiiuse会发现它。一看源代码显示如下加载它：
However, I'm wondering where to put the dll so that pywiiuse will find it. A look at the source shows that it is loaded as follows:
dll = ctypes.cdll.wiiuse
运行实例产生一个模块未发现异常时，我有在同一目录作为我的测试示例中的DLL。
Running examples yields a module not found exception when I have the dll in the same directory as my test example.
哪里看蟒蛇为DLL？
推荐答案
借助是记录在MSDN上。这不是Python特定的，有没有办法改变从命令行选项，搜索顺序。 （不过看到其他方式来影响搜索顺序链接的文章。）
The Windows DLL search order is documented on MSDN. It's not Python-specific, and there is no way to change the search order from a command-line option. (But see the linked article for other ways to influence the search order.)
源头上做：
from _ctypes import LoadLibrary as _dlopen
我没能找到的，但presumably它是Windows LoadLibraryEx ，其行为功能类似于POSIX 功能，因为那是它是如何使用的。
I wasn't able to find the definition of LoadLibrary in _ctypes.c, but presumably it is a wrapper for the Windows LoadLibraryEx function that behaves similarly to the POSIX dlopen function, because that is how it is used.
如果您可以修改Python源使用 ctypes.CDLL 的构造函数，而不是，它应该工作：
If you can modify the Python source to use the ctypes.CDLL constructor instead, it should work:
folder = os.path.dirname(os.path.abspath(__file__))
dll_path = os.path.join(folder, "wiiuse.dll")
dll = ctypes.CDLL(dll_path)
如果这是不可行的，你可以到猴子补丁ctypes的来处理这个具体案例，但似乎有点危险。也许只是复制DLL是在使用Python DLL的文件夹将是最简单的选择。
If that isn't viable, you may be able to monkey-patch ctypes to handle this specific case, but that seems a bit dangerous. Perhaps just copying the DLL to be in the same folder with the Python DLL would be the easiest alternative.
