That's possible. The loader provides several ways to go about solving this problem. The directory of the DLL can be added to the search path if you use LoadLibraryEx with the flag LOAD_WITH_ALTERED_SEARCH_PATH and use an absolute path. Python already does this for loading extension modules. If we didn't have to worry about older systems, in Windows 8/10 (and Vista/7 with KB2533623), the loader supports a set of flags that give detailed control of the DLL path, including LOAD_LIBRARY_SEARCH_DLL_LOAD_DIR. Individual directories can be added via AddDllDirectory and enabled via the flag LOAD_LIBRARY_SEARCH_USER_DIRS. Default flags can be set via SetDefaultDllDirectories, which affects LoadLibrary as well as LoadLibraryEx. On a related note, it would be nice to modify ctypes to call LoadLibraryEx instead of LoadLibrary. If the flags value is 0 the two calls are identical, so it wouldn't be a disruptive change. The existing dlopen "mode" parameter can be used for the flags, since it isn't used on Windows currently. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26071> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
