3.1.4.1 Sending Pending Notifications

The server notifies the client of pending notifications in one of three ways: by completing an asynchronous EcDoAsyncWaitEx RPC method call, by using push notifications and sending a UDP datagram to a callback address, or by sending a RopPending ROP response ([MS-OXCROPS] section 2.2.14.3). For more details about responding to an asynchronous RPC call, see section 3.1.5.3. For more details about using push notifications and sending a UDP datagram, see section 3.1.5.4. For more details about sending a RopPending ROP response, see section 3.1.5.6.
