# IOBluetoothDeviceSearchTypesBits

Bits to determine what Bluetooth devices to search for

```
struct IOBluetoothDeviceSearchTypesBits
```

## Overview

You can search for general device classes and service classes, or you can search for a specific device address or name. If you pass NULL as the attribute structure, you will get ALL devices in the vicinity found during a search. Note that passing a zeroed out block of attributes is NOT equivalent to passing in NULL!
