Hi all,

The Win32Utils team is happy to announce the release of win32-nio 0.0.1.

This is largely a proof of concept library, and should be considered  
alpha code.

= What is it?

Ruby’s IO methods implemented using native Windows function calls. In  
some cases  
the interface is slightly enhanced for Windows.

= What’s implemented?

At the moment there are only two methods, NIO.read and NIO.readlines.

= What are these enhancements you speak of?

In the case of NIO.read, it takes an optional 4th argument, which can be  
a  
Win32::Event object. Also, if a block is provided, it is treated as a  
callback  
that will fire when the read operation is complete.

= How do I get it?

gem install win32-nio.

It’s also available on the Win32Utils project page at  
[http://www.rubyforge.org/projects/win32utils](http://www.rubyforge.org/projects/win32utils).

Enjoy!

The Win32Utils Team
