[Opalvoip-devel] Own vxm session

[Denis <bab...@ma...>]

Hello.

I made my own vxml session like this:
class MyIVREndPoint : public OpalIVREndPoint
{
public:
        MyIVREndPoint(OpalManager & manager)
        : OpalIVREndPoint(manager) {}
        
        OpalIVRConnection * CreateConnection(
                OpalCall & call,        ///<  Owner of connection
                void * userData,        ///<  Arbitrary data to pass to connection
                const PString & vxml,   ///<  vxml to execute
                unsigned int options,
                OpalConnection::StringOptions * stringOptions = NULL
                );
};

class MyIVRConnection : public OpalIVRConnection
{
public:
        MyIVRConnection(
                OpalCall & call,            ///<  Owner calll for connection
                OpalIVREndPoint & endpoint, ///<  Owner endpoint for connection
                void * userData,            ///<  Arbitrary data to pass to connection
                const PString & vxml,       ///<  vxml to execute
                unsigned int options,
                OpalConnection::StringOptions * stringOptions = NULL
                );
};

class MyVXMLSession : public OpalVXMLSession 
{
public:
        MyVXMLSession(
                OpalConnection * conn,
                PTextToSpeech * tts = NULL,
                PBoolean autoDelete = PFalse
                );
};

OpalIVRConnection * MyIVREndPoint::CreateConnection(OpalCall & call,
                                                    void * userData,
                                                    const PString & vxml,
                                                    unsigned int options,
                                                    OpalConnection::StringOptions * stringOptions)
{
        return new MyIVRConnection(call, *this, userData, vxml, options, stringOptions);
}

MyIVRConnection::MyIVRConnection(OpalCall & call,
                                 OpalIVREndPoint & ep,
                                 void * userData,
                                 const PString & vxml,
                                 unsigned int options,
                                 OpalConnection::StringOptions * stringOptions)
: OpalIVRConnection(call, ep, userData, vxml, options, stringOptions)
{
        MyVXMLSession vxmlSession(this, PFactory<PTextToSpeech>::CreateInstance(ep.GetDefaultTextToSpeech()), true);
}

MyVXMLSession::MyVXMLSession(OpalConnection * conn,
                             PTextToSpeech * tts,
                             PBoolean autoDelete)
: OpalVXMLSession(conn, tts, autoDelete)
{ }


Why application crashes on exit:
void OpalManager::GarbageCollection()
{
  PBoolean allCleared = activeCalls.DeleteObjectsToBeRemoved();

  endpointsMutex.StartRead();

  for (PList<OpalEndPoint>::iterator ep = endpointList.begin(); ep != endpointList.end(); ++ep) {
    if (!ep->GarbageCollection()) <<-- "Access violation" exeception
      allCleared = false;
  }

  endpointsMutex.EndRead();

  if (allCleared && m_clearingAllCallsCount != 0)
    m_allCallsCleared.Signal();
}
