The NdkDisconnectEventCallbackEx (NDK_FN_DISCONNECT_EVENT_CALLBACK_EX) function is called by the NDK provider once when the peer disconnects.
DisconnectEventContext [in, optional]A context area that was specified in the DisconnectEvent parameter of the NdkCompleteConnectEx (NDK_FN_COMPLETE_CONNECT_EX) or NdkAcceptEx (NDK_FN_ACCEPT_EX) function when the completion queue (CQ) object was created.
ProviderDisconnectReason [in]A provider specific code that indicates why the connection has disconnected.
Zero indicates the NDK provider does not support the disconnect reason capability yet or did not provide one.
[!NOTE] This routine is implemented by the NDK consumer and passed to the NDK provider.
NdkDisconnectEventCallbackEx is a callback function for connection disconnect events. A disconnect notification callback function is specified for a connection with the NdkCompleteConnectEx (NDK_FN_COMPLETE_CONNECT_EX) function on the initiator side and with the NdkAcceptEx (NDK_FN_ACCEPT_EX) function on the listener side. The NDK provider invokes this callback only once when the peer disconnects. The provider should not flush outstanding work requests when it indicates a disconnect event because of an incoming disconnect request from the peer.
