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