# webContentProcessWithBundleID:interruptionHandler:completion:

Launches a web content extension process asynchronously.

```
+ (void) webContentProcessWithBundleID:(NSString *) bundleID interruptionHandler:(void (^)()) interruptionHandler completion:(void (^)(BEWebContentProcess *process, NSError *error)) completion;
```

## Parameters

`bundleID`

The bundle identifier of the web content extension to launch, or `nil` to use the default bundle identifier for this app’s web content extension.

`interruptionHandler`

A block the system calls if the web content extension process exits abnormally.

`completion`

A block the system calls when the process finishes launching.

## Discussion

Your browser app can run multiple web content extension processes.

The system guarantees that the process launched when it calls your completion handler.
