# sendData(toTransport:dataLength:)

You must override this to send data over your transport. This does nothing by default, it will return a kOBEXUnsupportedError.

## Declaration

```swift
func sendData(toTransport inDataToSend: UnsafeMutableRawPointer!, dataLength inDataLength: Int) -> OBEXError
```

## Parameters

- `inDataToSend`: Data to shove over the transport to a remote OBEX session.
- `inDataLength`: Length of data passed in.

## Discussion

Discussion Tranport subclasses must override this! When called you should send the data over the transport to the remote session.
