Hey all!
I've been struggling with this code for a while now.
I want to lookup MX-Records, thus, using the OpenTransport API
descriptions, i created the following piece of code:
/*
* CARBON CODE SNIPPET
*/
OSStatus err = noErr;
InetSvcRef inetServicesRef;
OTClientContextPtr contentPtr;
OTConfigurationRef configurationRef;
err = InitOpenTransportInContext(kInitOTForApplicationMask,
&contentPtr);
configurationRef = OTCreateConfiguration("udp");
if( configurationRef == NULL ) { std::cout << "invalid
config_ref!\n"; }
inetServicesRef = OTOpenInternetServicesInContext(configurationRef,
kO_NDELAY, &err, contentPtr);
// ....
/*
* END
*/
but, running this code results in inetServicesRef being NULL and a
-3282 error, aka, bad Configuration ref. I tried replacing it with
'kUDPName' and even 'kTCPName' (which obviously is the wrong protocol
for DNS, but tried anyway).
Anyone can give me any insight into my problem?
Hi Robert,
this code is definitely wrong. Here're some of my comments:
- You should not use UDP endpoint with Internet Services.
Use kDNRName rather than "udp".
- If you're using just kInitOTForApplicationMask in your app,
you can pass NULL for the context parameter in all calls.
- Use OTInetMailExchange to get MX record.
-Tomas
