|

|
|
* \brief Options for BCJ filters
|
||
|
|
*
|
||
|
|
* The BCJ filters never change the size of the data. Specifying options
|
||
|
|
* for them is optional: if pointer to options is NULL, default value is
|
||
|
|
* used. You probably never need to specify options to BCJ filters, so just
|
||
|
|
* set the options pointer to NULL and be happy.
|
||
|
|
*
|
||
|
|
* If options with non-default values have been specified when encoding,
|
||
|
|
* the same options must also be specified when decoding.
|
||
|
|
*
|
||
|
|
* \note At the moment, none of the BCJ filters support
|
||
|
|
* LZMA_SYNC_FLUSH. If LZMA_SYNC_FLUSH is specified,
|
||
|
|
* LZMA_OPTIONS_ERROR will be returned. If there is need,
|
||
|
|
* partial support for LZMA_SYNC_FLUSH can be added in future.
|
||
|
|
* Partial means that flushing would be possible only at
|
||
|
|
* offsets that are multiple of 2, 4, or 16 depending on
|
||
|
|
* the filter, except x86 which cannot be made to support
|
||
|
|
* LZMA_SYNC_FLUSH predictably.

* offset of the non-first sections so that the relative addresses
|

|
