> I am not sure if it's possible to also support Windows. For reference, FindFirstFileW doesn't support handle-relative names, and neither does CreateFileW. At a lower level in Windows NT, NtCreateFile has always supported handle-relative names, but CPython doesn't use the NT API. fd support (not dirfd) could be added to listdir and scandir in Windows. A directory can be listed via GetFileInformationByHandleEx: FileFullDirectoryInfo. This doesn't query the short name, so it may perform better than FindFirstFileW. However, opening a directory with os.open can't be supported. VC++ still hasn't documented the _O_OBTAIN_DIR (0x2000) flag. ---------- nosy: +eryksun _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39099> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
