Motivation

==========

Connecting to hostnames from EventMachine?  Dissatisfied from the

Dnsruby experience?  Disappointed by the lack of EventMachine support

in Dnsruby trunk?  Then you want this.

Usage

=====

        require 'em/resolver'

        

        EM.run {

          res = EventMachine::Resolver.new

          q = res.getaddrinfo("localhost")

          q.callback do |addresses|

            addresses.each { |address|

              spam! address

            }

          end

          q.errback do |error|

            puts "Oh noes: #{error}"

          end

        }

Dnsruby compatibility

=====================

A drop-in replacement for Dnsruby is provided given you use the

library exactly as stated in the [EventMachine FAQ](http://rubyeventmachine.com/wiki/FAQ#DoesEMblockonDNSresolutionsi.e.ifyoustartaconnectiontotakes_ages.comwillittemporarilyblocktheotherprocesseswhileitworks).

See spec/dnsruby_spec.rb for details.

ext/asyncns.h

=========

...is included in a slightly modified form because the original one

had parameter names like `class' which prevents compiling as C++.
