@a11r This is the API we discussed for async server side cancellation monitoring. |
| // Async only. Has to be called before the rpc starts. | ||
| // Returns the tag in completion queue when the rpc finishes. | ||
| // IsCancelled() can then be called to check whether the rpc was cancelled. | ||
| void AsyncNotifyWhenDone(void* tag) { async_notify_when_done_tag_ = tag; } |
