# setProperty(const char *, bool)

Synchronized method to construct and add an OSBoolean property to a registry entry's property table.

## Declaration

```occ
virtual bool setProperty(
 const char *aKey,
 boolaBoolean); 
```

## Parameters

- `aKey`: The property's name as a C-string.
- `aBoolean`: The property's boolean value.

## Return Value

Return Value true on success or false on a resource failure.

## Overview

Overview This method will add or replace a property in a registry entry's property table, using the OSDictionary::setObject semantics. This method is synchronized with other IORegistryEntry accesses to the property table. The property is created as an OSBoolean from the supplied value, set in the property table with the given name, and released.
