File::Constants
File::Constants provides file-related constants. All possible file constants are listed in the documentation but they may not all be present on your platform.
If the underlying platform doesn't define a constant the corresponding Ruby constant is not defined.
Your platform documentations (e.g. man open(2)) may describe more detailed information.
