IRTCSession2

  • Article

The IRTCSession2 interface contains additional methods and properties related to the session, extending the functionality provided by the IRTCSession interface. The IRTCClient::CreateSession and IRTCClient2::CreateSessionWithDescription methods create the Session object. Use QueryInterface on the Session object to discover the IRTCSession2 interface for RTC 1.2 implementations.
