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_BEOS_HLEN ) bytes of data, and full_size
|
|
should equal ( ef_size - EB_BEOS_HLEN ).
|
|
|
|
If the data is compressed, there will be ( ef_size - EB_BEOS_HLEN ) 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\0 - C string
|
|
struct attr_info (fields in big-endian format)
|
|
attr_data (length in attr_info.size)
|
