## Declaration

```occ
virtual void output(
 IOMbufQueue *queue,
 UInt32 *state); 
```

## Parameters

- `queue`: A queue of output packets.
- `state`: Returns a state bit defined by IOBasicOutputQueue that declares the new state of the queue following this method call. A kStateStalled is returned if the queue should stall, otherwise 0 is returned.
