# init

## Declaration

```occ
virtual bool init(
 OSDictionary *properties); 
```

## Overview

Overview This function is overridden so that IOBlockStorageDevice can set a property, used by IOBlockStorageDriver for matching. Since the concrete subclass of IOBlockStorageDevice can be of any class type, the property is used for matching. This function is usually not overridden by developers.
