# UserAbortTaskSetRequest

Aborts all tasks in a logical unit.

## Declaration

```occ
virtual kern_return_t UserAbortTaskSetRequest(uint64_t theT, uint64_t theL, uint32_t *response);
```

## Parameters

- `theT`: The target containing the tasks to abort.
- `theL`: The logical unit containing the tasks to abort.
- `response`: On return, a SCSI protocol-specific value indicating the success or failure of the request.

## Discussion

Discussion This method doesn’t clear previously established conditions, such as MODE SELECT parameters, reservations, and autocontingent allegiance (ACA) attributes.
