netsnmp_mib_handler netsnmp_get_timed_bare_stash_cache_handler (int timeout, oid *rootoid, size_t rootoid_len)
  returns a stash_cache handler that can be injected into a given handler chain (with the specified timeout and root OID values), but *only* if that handler chain explicitly supports stash cache processing.
netsnmp_mib_handler netsnmp_get_bare_stash_cache_handler (void)
  returns a single stash_cache handler that can be injected into a given handler chain (with a fixed timeout), but *only* if that handler chain explicitly supports stash cache processing.
netsnmp_mib_handler netsnmp_get_stash_cache_handler (void)
  returns a stash_cache handler sub-chain that can be injected into a given (arbitrary) handler chain, using a fixed cache timeout.
netsnmp_mib_handler netsnmp_get_timed_stash_cache_handler (int timeout, oid *rootoid, size_t rootoid_len)
  returns a stash_cache handler sub-chain that can be injected into a given (arbitrary) handler chain, using a configurable cache timeout.

Detailed Description

Automatically caches data for certain handlers.

This handler caches data in an optimized way which may aleviate the need for the lower level handlers to perform as much optimization. Specifically, somewhere in the lower level handlers must be a handler that supports the MODE_GET_STASH operation. Note that the table_iterator helper supports this.
