- * just like a template in C++, this macro does cache lookup
- * for us.
- * The function is passed some sort of HANDLE from which a cache_detail
- * structure can be determined (via SETUP, DETAIL), a template
- * cache entry (type RTN*), and a "set" flag.  Using the HASHFN and the 
- * TEST, the function will try to find a matching cache entry in the cache.
- * If "set" == 0 :
- *    If an entry is found, it is returned
- *    If no entry is found, a new non-VALID entry is created.
- * If "set" == 1 and INPLACE == 0 :
- *    If no entry is found a new one is inserted with data from "template"
- *    If a non-CACHE_VALID entry is found, it is updated from template using UPDATE
- *    If a CACHE_VALID entry is found, a new entry is swapped in with data
- *       from "template"
- * If set == 1, and INPLACE == 1 :
- *    As above, except that if a CACHE_VALID entry is found, we UPDATE in place
- *       instead of swapping in a new entry.
- *
- * If the passed handle has the CACHE_NEGATIVE flag set, then UPDATE is not
- * run but insteead CACHE_NEGATIVE is set in any new item.
- *  In any case, the new entry is returned with a reference count.
