# sessionKeepCurrentBootstrap

The caller has allocated sub-bootstrap.

```
static var sessionKeepCurrentBootstrap: SessionCreationFlags { get }
```

## Discussion

If you create a subset port on your own, you can force

the [`SessionCreate(_:_:)`](/documentation/Security/SessionCreate(_:_:)) function to use it by passing this flag in the `flags` parameter. However, you can’t supersede a prior call that way; only a single [`SessionCreate(_:_:)`](/documentation/Security/SessionCreate(_:_:)) call is allowed for each session.
