RubyCocoa で SCNetworkReachability を使う

RubyCocoa で SCNetworkReachability を使ってみました。

require 'osx/foundation'
OSX.require_framework '/System/Library/Frameworks/SystemConfiguration.framework'
include OSX

# Reachability Call Back
networkReachabilityCallBack = proc do |target, flags, info|
  print "NetworkReachabilityCallBack: %d\n" % flags
end

# Initialize Reachablity
reachability = SCNetworkReachabilityCreateWithName(nil, "balunsoftware.jp")
unless reachability != nil
  print "SCNetworkReachabilityCreateWithName error"
  exit 1
end
unless SCNetworkReachabilitySetCallback(reachability, networkReachabilityCallBack, nil)
  print "SCNetworkReachabilitySetCallback error"
  exit 1
end
unless SCNetworkReachabilityScheduleWithRunLoop(reachability, CFRunLoopGetCurrent(), KCFRunLoopDefaultMode)
  print "SCNetworkReachabilityScheduleWithRunLoop error"
  exit 1
end

begin
  CFRunLoopRun()
rescue Interrupt
end
