| /* 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. |
