# SetClockAlgorithm

Sets the clock algorithm of the clock device.

```
kern_return_t SetClockAlgorithm(IOUserAudioClockAlgorithm in_clock_algorithm);
```

## Parameters

`in_clock_algorithm`

The clock algorithm to set.

## Return Value

<doc://com.apple.documentation/documentation/DriverKit/kIOReturnSuccess> on success, or another value if an error occurs. For a list of error codes, see <doc://com.apple.documentation/documentation/DriverKit/error-codes>.

## Discussion

Drivers can change the transport type of the clock device dynamically. If successful, changing the transport type sends a notification to the host to update the object state.
