Of course I meant: PendingIODevice *offerTube(const QHostAddress &address, const QVariantMap ¶meters); And in Account: PendingChannelRequest *createStreamTube( const ContactPtr &contact, const QString &serviceName, const QDateTime &userActionTime = QDateTime::currentDateTime(), const QString &preferredHandler = QString()); > > QHostAddress should already nicely encapsulate the needed logic for > address_type+address, I would appreciate if one of you could confirm that. > > I am wondering if I should also expose socket_access_control: in case it's > not needed, what's a sensible default?
