| 19 | DR9 'Be' extra-field layout: |
||
| 20 | |||
| 21 | 'Be' - signature |
||
| 22 | ef_size - size of data in this EF (little-endian unsigned short) |
||
| 23 | full_size - uncompressed data size (little-endian unsigned long) |
||
| 24 | flag - flags (byte) |
||
| 25 | flags & EB_BE_FL_UNCMPR = the data is not compressed |
||
| 26 | flags & EB_BE_FL_BADBITS = the data is corrupted or we |
||
| 27 | can't handle it properly |
||
| 28 | data - compressed or uncompressed file attribute data |
||
| 29 | |||
| 30 | If flag & EB_BE_FL_UNCMPR, the data is not compressed; this optimisation is |
||
| 31 | necessary to prevent wasted space for files with small attributes (which |
||
| 32 | appears to be quite common on the Advanced Access DR9 release). In this |
||
| 33 | case, there should be ( ef_size - EB_BEOS_HLEN ) bytes of data, and full_size |
||
| 34 | should equal ( ef_size - EB_BEOS_HLEN ). |
||
| 35 | |||
| 36 | If the data is compressed, there will be ( ef_size - EB_BEOS_HLEN ) bytes of |
||
| 37 | compressed data, and full_size bytes of uncompressed data. |
||
| 38 | |||
| 39 | If a file has absolutely no attributes, there will not be a 'Be' extra field. |
||
| 40 | |||
| 41 | The uncompressed data is arranged like this: |
||
| 42 | |||
| 43 | attr_name\0 - C string |
||
| 44 | struct attr_info (fields in big-endian format) |
||
| 45 | attr_data (length in attr_info.size) |
