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, and NIO.readlines.

= What are these enhancements you speak of?

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

= How do I get it?

gem install win32-nio.
