# getStreamsTo(_:port:inputStream:outputStream:)

Creates and returns by reference an `NSInputStream` object and `NSOutputStream` object for a socket connection with a given host on a given port.

```
class func getStreamsTo(_ host: Host, port: Int, inputStream: AutoreleasingUnsafeMutablePointer<InputStream?>?, outputStream: AutoreleasingUnsafeMutablePointer<OutputStream?>?)
```

## Parameters

`host`

The host to which to connect.

`port`

The port to connect to on `host`.

`inputStream`

Upon return, contains the input stream. If `nil` is passed, the stream object is not created.

`outputStream`

Upon return, contains the output stream. If `nil` is passed, the stream object is not created.

## Discussion

If neither `port` nor `host` is properly specified, no socket connection is made.
