c++ ptlib PNotifier在OPAL中的应用

Question

我正在使用OpalVoip制作一个软电话应用程序，但我遇到了以下问题：

void MyManager::main()
{
    //variables
    PNotifier notify; // this is the problem
    //it is the template PNotifierFunctionTemplate<INT>

    //more stuff 

    listener->Open(notify); 

    //listener is of type OpalListenerUDP
    //it should start the listener and wait for incoming connection
    //but however i need to pass this NOTIFY which should be the INT parameter to the
    //new OpalTransport instance created by the listener...
    //however OpalListenerUDP only creates OpalTransport after the connection is
    //accepted as so in following: OpalListenerUDP::Accept(/*time interval*/)
    //
    //So far I think that this notifier should be a pointer to an object of type
    //OpalListenerUDP but i have no idea how to get it done 
}

任何帮助都会很感激的，瑞德。

经过对opal源代码的深入研究，我找到了解决方案。事实证明，

OpalConnection::StartListener(OpalListener&);

将执行打开侦听器的工作，因此不需要调用OpalListener::Open()，因此只需调用OpalListener::Accept即可接受连接。
