# BEExtensionProcess

A common protocol that creates XPC connections for an extension process.

```
protocol BEExtensionProcess : NSObjectProtocol
```

## Overview

This protocol is common across extension processes for networking ([`BENetworkingProcess`](/documentation/BrowserEngineKit/BENetworkingProcess)), rendering ([`BERenderingProcess`](/documentation/BrowserEngineKit/BERenderingProcess)), and web content ([`BEWebContentProcess`](/documentation/BrowserEngineKit/BEWebContentProcess)).

Create an XPC connection for an extension process with the <doc://com.apple.documentation/documentation/BrowserEngineKit/BEExtensionProcess/makeLibXPCConnectionError()> method. Stop an extension process with <doc://com.apple.documentation/documentation/BrowserEngineKit/BEExtensionProcess/invalidate()>.

## Topics

Managing extension connections

[`invalidate()`](/documentation/BrowserEngineKit/BEExtensionProcess/invalidate())

Stops the extension process.

[`makeLibXPCConnectionError()`](/documentation/BrowserEngineKit/BEExtensionProcess/makeLibXPCConnectionError())

Creates a new libXPC connection to the extension process.
