- DR9 'Be' extra-field layout:
- 'Be' - signature
- ef_size - size of data in this EF (little-endian unsigned short)
- full_size - uncompressed data size (little-endian unsigned long)
- flag - flags (byte)
- flags & EB_BE_FL_UNCMPR = the data is not compressed
- flags & EB_BE_FL_BADBITS = the data is corrupted or we
- can't handle it properly
- data - compressed or uncompressed file attribute data
- If flag & EB_BE_FL_UNCMPR, the data is not compressed; this optimisation is
- necessary to prevent wasted space for files with small attributes (which
- appears to be quite common on the Advanced Access DR9 release). In this
- case, there should be ( ef_size - EB_L_BE_LEN ) bytes of data, and full_size
- should equal ( ef_size - EB_L_BE_LEN ).
- If the data is compressed, there will be ( ef_size - EB_L_BE_LEN ) bytes of
- compressed data, and full_size bytes of uncompressed data.
- If a file has absolutely no attributes, there will not be a 'Be' extra field.
- The uncompressed data is arranged like this:
- attr_name - C string
- struct attr_info (fields in big-endian format)
- attr_data (length in attr_info.size)
