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.
