otSrpServerServiceUpdateHandler

Handles SRP service updates. Is called by the SRP server to notify that a SRP host and possibly SRP services are being updated. It is important that the SRP updates are not committed until the handler returns the result by calling otSrpServerHandleServiceUpdateResult or times out after @p aTimeout. A SRP service observer should always call otSrpServerHandleServiceUpdateResult with error code OT_ERROR_NONE immediately after receiving the update events. A more generic handler may perform validations on the SRP host/services and rejects the SRP updates if any validation fails. For example, an Advertising Proxy should advertise (or remove) the host and services on a multicast-capable link and returns specific error code if any failure occurs. @sa otSrpServerSetServiceUpdateHandler @sa otSrpServerHandleServiceUpdateResult
