For example: if the max key length in words is 128, including space for a null terminator, lenMaxStringKeyInUnits must be 128. 3) keyStorageMethod: only MapHashTable is currently supported 4) fReplaceDuplicateKeyCacheEntry: a global setting, which causes the Insert methods to replace duplicate key cache entries. 5) numSecondsTTLDefault: the default Time-to-live (TTL) value 6) pHashFunctionStructure: must point to a HashFunctionStructure that has been initialized with a hash function. 7) replacementPolicy: LRU or LFU 8) numDirectoryElementsToAllocate: size of map (hash table). A typical value would be 133% the size of the cache. (E.g. if cache size = 1000, this would be 1333). 9) sizeCache: the number of entries (array elements) of the cache 10) pGlobalConfiguration: a pointer to a GlobalConfiguration structure (may be NULL, if custom global configuration settings are not needed). 11) fDEBUG: for debugging 12) pLogger: a pointer to an initialized CLogger object. Return values: E_CACHE_INITIALIZATION_INVALID_KEYTYPE_FOR_MAPHASHTABLE E_INSUFFICIENTMEMORY E_CACHE_INITIALIZATION_INVALID_KEYSTORAGEMETHOD E_KEY_INVALIDKEYTYPE E_CACHE_INITIALIZATION_CACHESIZE_TOO_SMALL E_CACHE_INITIALIZATION_INVALID_REPLACEMENTPOLICY E_LOGGINGFUNCTION_MISSING E_SUCCESS Glenn HoffordSat, 10 Dec 2011 04:41:45 -0000https://sourceforge.netd93e57ab438298ace766d22c1831f58c118e6848
