Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

This change synchronize header files ecma_167.h and osta_udf.h with
udftools 2.2 project which already have definitions for UDF 2.60 revision.
In most cases there are only changes in comments and added new definitions
and done. There are no functional changes in code. Visible changes are:

1. Removed duplicate definition of UDF_ID_COMPLIANT macro.

2. Moved OSTA Identifier Suffix macros from ecma_167.h to osta_udf.h,
changed its naming and types (endianity fix) to match naming convention
with other UDF structures.

3. Renamed EXT_NEXT_EXTENT_ALLOCDECS macro to EXT_NEXT_EXTENT_ALLOCDESCS as
"desc" abbrev (and not "dec") is used on all other places.
