# setProperties

Optionally supported external method to set properties in a registry entry.

## Declaration

```occ
virtual IOReturn setProperties(
 OSObject *properties ); 
```

## Parameters

- `properties`: Any OSObject subclass, to be interpreted by the implementing method - for example an OSDictionary, OSData etc. may all be appropriate.

## Return Value

Return Value An IOReturn code to be returned to the caller.

## Overview

Overview This method is not implemented by IORegistryEntry, but is available to kernel and non-kernel clients to set properties in a registry entry. IOUserClient provides connection based, more controlled access to this functionality and may be more appropriate for many uses, since there is no differentiation between clients available to this method.
