- /* BMK_benchFiles() :
- * Benchmark all files provided through array @fileNamesTable.
- * All files must be valid, otherwise benchmark fails.
- * Roundtrip measurements are done for each file individually, but
- * unless BMK_setBenchSeparately() is set, all results are agglomerated.
- * The method benchmarks all compression levels from @cLevelStart to @cLevelLast,
- * both inclusive, providing one result per compression level.
- * If @cLevelLast <= @cLevelStart, BMK_benchFiles() benchmarks @cLevelStart only.
- * @dictFileName is optional, it's possible to provide NULL.
- * When provided, compression and decompression use the specified file as dictionary.
- * Only one dictionary can be provided, in which case it's applied to all benchmarked files.
