* Document-module: Errno
|
|
*
|
|
* Ruby exception objects are subclasses of <code>Exception</code>.
|
|
* However, operating systems typically report errors using plain
|
|
* integers. Module <code>Errno</code> is created dynamically to map
|
|
* these operating system errors to Ruby classes, with each error
|
|
* number generating its own subclass of <code>SystemCallError</code>.
|
|
* As the subclass is created in module <code>Errno</code>, its name
|
|
* will start <code>Errno::</code>.
|
|
*
|
|
* The names of the <code>Errno::</code> classes depend on
|
|
* the environment in which Ruby runs. On a typical Unix or Windows
|
|
* platform, there are <code>Errno</code> classes such as
|
|
* <code>Errno::EACCES</code>, <code>Errno::EAGAIN</code>,
|
|
* <code>Errno::EINTR</code>, and so on.
|
|
*
|
|
* The integer operating system error number corresponding to a
|
|
* particular error is available as the class constant
|
|
* <code>Errno::</code><em>error</em><code>::Errno</code>.
|
|
*
|
|
* Errno::EACCES::Errno #=> 13
|
|
* Errno::EAGAIN::Errno #=> 11
|
|
* Errno::EINTR::Errno #=> 4
|
|
*
|
|
* The full list of operating system errors on your particular platform
|
|
* are available as the constants of <code>Errno</code>.
|
|
*
|
|
* Errno.constants #=> E2BIG, EACCES, EADDRINUSE, EADDRNOTAVAIL, ...
