i really don't know how to convert the example provided by apple into macruby code, since address is a char pointer, irghhh:
SCNetworkReachabilityRef target;
SCNetworkConnectionFlags flags = 0;
Boolean ok;
target = SCNetworkReachabilityCreateWithAddress(NULL, address);
ok = SCNetworkReachabilityGetFlags(target, &flags);
CFRelease(target);
here is an example implementation in Objective-C:
Determining Internet Availability on iPhone?
UPDATE:
i just realized, that i can do it very quickly with macruby itself, but i am stil interested in how you would do this with macruby.
def network_available?
Socket.getaddrinfo('example.com', nil)
rescue
false
end
You should simply get the pointer of your MacRuby NSString instance:
address = "example.com".pointer
...
target = SCNetworkReachabilityCreateWithAddress(NULL, address)
