- * \brief       Finds out the minimal reasonable chunk size for a filter chain
- *
- * This function helps determining the Uncompressed Sizes of the Blocks when
- * doing multi-threaded encoding.
- *
- * When compressing a large file on a system having multiple CPUs or CPU
- * cores, the file can be split into smaller chunks, that are compressed
- * independently into separate Blocks in the same .lzma Stream.
- *
- * \return      Minimum reasonable Uncompressed Size of a Block. The
- *              recommended minimum Uncompressed Size is between this value
- *              and the value times two.
-
- Zero if the Uncompressed Sizes of Blocks don't matter
