| 11 // This sub-API supports the following functionalities: | |
| 12 // | |
| 13 // - External protocol support. | |
| 14 // - Packet timeout notification. | |
| 15 // - Dead-or-Alive connection observations. | |
| 16 // | |
| 17 // Usage example, omitting error checking: | |
| 18 // | |
| 19 // using namespace webrtc; | |
| 20 // VoiceEngine* voe = VoiceEngine::Create(); | |
| 21 // VoEBase* base = VoEBase::GetInterface(voe); | |
| 22 // VoENetwork* netw = VoENetwork::GetInterface(voe); | |
| 23 // base->Init(); | |
| 24 // int ch = base->CreateChannel(); | |
| 25 // ... | |
| 26 // netw->SetPeriodicDeadOrAliveStatus(ch, true); | |
| 27 // ... | |
| 28 // base->DeleteChannel(ch); | |
| 29 // base->Terminate(); | |
| 30 // base->Release(); | |
| 31 // netw->Release(); | |
