| Fred Drake | de69ae1 | 1999-06-17 17:40:52 +0000 | [diff] [blame] | 11 | The \module{cmpcache} module provides an identical interface and similar |
| 12 | functionality as the \refmodule{cmp} module, but can be a bit more efficient |
| 13 | as it uses \function{statcache.stat()} instead of \function{os.stat()} |
| 14 | (see the \refmodule{statcache} module for information on the |
| 15 | difference). |

| Fred Drake | de69ae1 | 1999-06-17 17:40:52 +0000 | [diff] [blame] | 17 | \strong{Note:} Using the \refmodule{statcache} module to provide |
| 18 | \function{stat()} information results in trashing the cache |
| 19 | invalidation mechanism: results are not as reliable. To ensure |
| 20 | ``current'' results, use \function{cmp.cmp()} instead of the version |
| 21 | defined in this module, or use \function{statcache.forget()} to |
| 22 | invalidate the appropriate entries. |
