# OSBoolean

OSBoolean wraps a boolean value in a C++ object for use in Libkern collections.

## Declaration

```occ
class OSBoolean : OSObject
```

## Overview

Overview OSBoolean represents a boolean true/false value as a Libkern C++ object. There are only two instances of OSBoolean, kOSBooleanTrue and kOSBooleanFalse. These are shared globally and returned by the instance-creation function withBoolean. Thus, you can use pointer comparison to test whether two OSBoolean objects are equal.
