# AbortDeviceConfigurationChange

The host calls this method to tell the driver not to perform a
configuration change it requested by calling
RequestDeviceConfigurationChange(). Subclass and override this method to handle any
aborted custom configuration change requests. Then call the superclass implementation to update state.

```
virtual kern_return_t AbortDeviceConfigurationChange(uint64_t in_change_action, OSObject *in_change_info);
```

## Parameters

`in_change_action`

A uint64_t indicating the action the device object wants to take. This is
the same value passed to RequestDeviceConfigurationChange().
Note that this value is purely for the driver’s usage. The host does
not look at this value.

`in_change_info`

A pointer to an OSObject about the configuration change. This is the
same value passed to RequestDeviceConfigurationChange(). Note
that this value is purely for the driver’s usage. The host does not
look at this value. Retain or release the object reference as necessary.

## Return Value

A kern_return_t value indicating success or failure.
