# SetOutputLatency

Sets the output latency of the clock device.

## Declaration

```occ
kern_return_t SetOutputLatency(uint32_t in_latency);
```

## Parameters

- `in_latency`: uint32_t output latency value to set.

## Discussion

Discussion Drivers can change the latency of the clock device dynamically. The object sends a notification to the host to update the object state on success. The object’s work queue synchronizes access to the value.
