c++ - c++ ptlib PNotifier use in OPAL

Question

I'm using OpalVoip for making a softphone application and i got stuck with following:

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 
}

Any help will be appreciated, Red.

在对蛋白石源代码进行深入研究后，我找到了解决方案。事实证明

OpalConnection::StartListener(OpalListener&);

将完成打开侦听器的工作，因此无需调用 OpalListener::Open() ，因此只需调用 OpalListener::Accept 即可接受连接。
