|Parameters||strio||The stream to which to write bytes (type: File-like object )|
|compDict||A dictionary of backreference addresses that have have already been
written to this stream and that may be used for compression.
|Parameters||strio||The stream from which bytes may be read (type: File-like object )|

ignore this value. Only in the case of records similar to TXT where the
total length is in no way encoded in the data is it necessary.
