35// This file contains the declarations for Windows implementations of
36// commonly used POSIX functions such as open(2) and access(2), as well
37// as macro definitions for flags of these functions.
38//
39// By including this file you'll redefine open/access/etc. to
40// ::google::protobuf::io::win32::{open/access/etc.}.
41// Make sure you don't include a header that attempts to redeclare or
42// redefine these functions, that'll lead to confusing compilation
43// errors. It's best to #include this file as the last one to ensure that.
44//
45// This file is only used on Windows, it's empty on other platforms.
