NAME
       netsnmpstashcache - automatically caches data for certain handlers.



   Functions
       netsnmpstashcacheinfo * netsnmpgetnewstashcache (void)
       netsnmpmibhandler * netsnmpgetstashcachehandler (void)
           returns a stashcache handler that can be injected into a given
           handler chain.
       netsnmpoidstashnode ** netsnmpextractstashcache
           (netsnmpagentrequestinfo *reqinfo)
           extracts a pointer to the stashcache info from the reqinfo
           structure.
       int netsnmpstashcachehelper (netsnmpmibhandler *handler,
           netsnmphandlerregistration *reginfo, netsnmpagentrequestinfo
           *reqinfo, netsnmprequestinfo *requests)
       int netsnmpstashcacheupdate (netsnmpmibhandler *handler,
           netsnmphandlerregistration *reginfo, netsnmpagentrequestinfo
           *reqinfo, netsnmprequestinfo *requests, netsnmpstashcacheinfo
           *cinfo)
           updates a given cache depending on whether it needs to or not.
       void netsnmpinitstashcachehelper (void)
           initializes the stashcache helper which then registers a
           stashcache handler as a run-time injectable handler for
           configuration file use.

Detailed Description
       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 MODEGETSTASH operation. Note that the
       tableiterator helper supports this.
