'cache' is the data structure controlling the cache handling. You probably don't want to meddle with this. The one exception is that it includes a field 'magic' which can be used to pass the data that's loaded between the XXX_load routine, and wherever it's actually needed. Use 'netsnmp_extract_cache_info' (or netsnmp_cache_reqinfo_extract) to retrieve this cache within the handler. Alternatively you can just use a global variable! I can't remember what vmagic is - it's probably a read-only version of the same hook. > Do these two patameters take some index parameters? > I want to load data according to index.Can I do such? No - the idea of the cache helper is that it will load *all* of the data relating to a particular table. The table handler can then pick through it, to find the bits that are needed for a given request. The cache helper will hold on to that internal cache until it's regarded as "too old" to be useful. Then it will release it, and the next request will trigger a reload of a fresh copy.
