```csharp
bool IsCompleted(EventID id)
```

### Parameters

**** (\[EventID]\(/engine/6000.5/script-reference/unityengine/lighttransport/eventid)): ID of the event to query.

### Returns

| Type                                                          | Description                                       |

| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | True if the asynchronous operation has completed. |

### Remarks

This method returns immediately and does not wait for the operation to complete. Use [IDeviceContext.Flush()](/engine/6000.5/script-reference/unityengine/lighttransport/idevicecontext/flush.md) to force the device implementation to start processing commands. Use [IDeviceContext.Wait](/engine/6000.5/script-reference/unityengine/lighttransport/idevicecontext/wait.md) to busy-wait for a specific event.
