The mapping to POSIX open flags is from a table in the POSIX fopen spec [1] as well as the Windows CRT docs for fopen (see the equivalent oflag table) [2]. The flags for "x" mode can be verified in the Python 3 source [3]. The "x" mode flags are also mentioned in GNU's libc docs for fopen [4] and open-time flags [5]. The mapping from POSIX open flags to Windows create disposition and access modes is from the CRT source for the _open function. I can't provide a source link, but the source code is distributed with MSVC. For VS2015 it's in lowio/open.cpp, decode_access_flags() and decode_open_create_flags().
