I believe that there is a subtle difference in the entry-point depending on whether the file is named .pyd or .dll. http://effbot.org/pyfaq/is-a-pyd-file-the-same-as-a-dll.htm https://docs.python.org/2/faq/windows.html#is-a-pyd-file-the-same-as-a-dll I'm not entirely sure, but I think the only way to access a DLL proper is via cytpes (or some other third-party framework, like Boost or SWIG). To actually use "import spam" on a DLL, you have to make sure it has an initfoo() function, and declare the list of available functions somewhat differently. Oh, and according to this: https://docs.python.org/2/extending/windows.html prior to Python 2.5, spam.dll was recognised by import. That was specifically changed so that you could have a spam.dll C library and a spam.pyd interface to that library. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
