# deadline

The deadline by which your app must respond to the event.

```
var deadline: UInt64
```

## Discussion

If you fail to respond to an event before this deadline, Endpoint Security may terminate the client process, or restart the process if it’s a system extension. If your client repeatedly misses deadlines, Endpoint Security may refuse new connections from [`es_new_client(_:_:)`](/documentation/EndpointSecurity/es_new_client(_:_:)) altogether.
