NAME
stash_cache: 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.
Functions
netsnmp_stash_cache_info * netsnmp_get_new_stash_cache (void)
netsnmp_mib_handler * netsnmp_get_stash_cache_handler (void)
returns a stash_cache handler that can be injected into a given handler chain.
netsnmp_oid_stash_node ** netsnmp_extract_stash_cache (netsnmp_agent_request_info *reqinfo)
extracts a pointer to the stash_cache info from the reqinfo structure.
int netsnmp_stash_cache_helper (netsnmp_mib_handler *handler, netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo, netsnmp_request_info *requests)
int netsnmp_stash_cache_update (netsnmp_mib_handler *handler, netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo, netsnmp_request_info *requests, netsnmp_stash_cache_info *cinfo)
updates a given cache depending on whether it needs to or not.
void netsnmp_init_stash_cache_helper (void)
initializes the stash_cache helper which then registers a stash_cache 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 MODE_GET_STASH operation. Note that the table_iterator helper supports this.
