* For example, to probe for a SRV record:
|
|
*
|
|
* @code
|
|
* QMdnsEngine::Record record;
|
|
* record.setName("My Service._http._tcp.local.");
|
|
* record.setType(QMdnsEngine::SRV);
|
|
* record.setPort(1234);
|
|
* record.setTarget(hostname.hostname());
|
|
*
|
|
* QMdnsEngine::Prober prober(&server, record);
|
|
* connect(&prober, &QMdnsEngine::Prober::nameConfirmed, [](const QByteArray &name) {
|
|
* qDebug() << "Name confirmed:" << name;
|
|
* });
