# SetStreamIsActive

Sets whether that the stream is active and doing IO.

## Declaration

```occ
kern_return_t SetStreamIsActive(bool in_is_active);
```

## Parameters

- `in_is_active`: True if the stream is enabled and doing IO; otherwise, false.

## Discussion

Discussion Changing the stream active state will send a notification to the host to update the object state if successful. The object’s work queue synchronizes access to the stream active state.
