# ODQueryScheduleWithRunLoop(_:_:_:)

Retrieves results from a query asynchronously by scheduling the query in a run loop.

```
func ODQueryScheduleWithRunLoop(_ query: ODQueryRef!, _ runLoop: CFRunLoop!, _ runLoopMode: CFString!)
```

## Parameters

`query`

The query.

`runLoop`

The run loop.

`runLoopMode`

The mode of the run loop.

## Discussion

This function spawns a new thread to execute the query in `inRunLoop`. When the query is complete, the query’s callback function is called with both `inResults` and `inError` set to `NULL`. To remove an incomplete query from its run loop, call [`ODQueryUnscheduleFromRunLoop(_:_:_:)`](/documentation/OpenDirectory/ODQueryUnscheduleFromRunLoop(_:_:_:)).

## See Also

[`ODQueryCallback`](/documentation/OpenDirectory/ODQueryCallback)

A callback function called as results from a scheduled query are returned.
