// This sub-API supports the following functionalities:
|
|
//
|
|
// - External protocol support.
|
|
// - Packet timeout notification.
|
|
// - Dead-or-Alive connection observations.
|
|
//
|
|
// Usage example, omitting error checking:
|
|
//
|
|
// using namespace webrtc;
|
|
// VoiceEngine* voe = VoiceEngine::Create();
|
|
// VoEBase* base = VoEBase::GetInterface(voe);
|
|
// VoENetwork* netw = VoENetwork::GetInterface(voe);
|
|
// base->Init();
|
|
// int ch = base->CreateChannel();
|
|
// ...
|
|
// netw->SetPeriodicDeadOrAliveStatus(ch, true);
|
|
// ...
|
|
// base->DeleteChannel(ch);
|
|
// base->Terminate();
|
|
// base->Release();
|
|
// netw->Release();
|
|
// VoiceEngine::Delete(voe);
