| Parameter | Description |
|---|---|
| baseline | The previous 8-byte unsigned long value, used to compute the diff. |
| model | StreamCompressionModel model for reading value in a packed manner. |
ulong An 8-byte unsigned long read from the current stream, or 0 if the end of the stream has been reached. If the data did not change, this also returns 0. See: DataStreamReader.HasFailedReads to verify if the read failed.
Reads an 8-byte unsigned long delta value from the data stream using a StreamCompressionModel.
