As Dave says there is no helper for this.
This code is part of a test program I have (the module is named indexes,
you may wish to do a search and replace to change the name to something
better, also you might have to remove some const's as I tend to add them
generously and the old code might fail to handle all the ones that I
use).
static int
handle_table(netsnmp_mib_handler* handler,
netsnmp_handler_registration* reginfo,
netsnmp_agent_request_info* reqinfo,
netsnmp_request_info* requests)
{
netsnmp_request_info* r;
netsnmp_table_request_info* tri;
netsnmp_variable_list* vl;
for (r = requests; r; r = r->next) {
tri = netsnmp_extract_table_info(r);
if (!tri)
continue;
/* Here *vl contains the ip address and
* *vl->next_variable contains the port
* Note that this only extracts the indices, it is up to you
* to handle getnext requests properly!
*/
}
}
return SNMP_ERR_NOERROR;
}
static const oid indexes_oid[] = { 1, 3, 6, 1, 4, 1, 8072, 9999, 9999,
4711 };
void
init_indexes(void)
{
netsnmp_handler_registration *reg =
netsnmp_create_handler_registration(
"indexes", handle_table,
indexes_oid, OID_LENGTH(indexes_oid),
HANDLER_CAN_RONLY);
netsnmp_table_registration_info *table_info =
SNMP_MALLOC_TYPEDEF(netsnmp_table_registration_info);
netsnmp_table_helper_add_indexes(
table_info,
ASN_IPADDRESS, ASN_INTEGER,
0);
table_info->min_column = 2; /* adopt this to your situation */
table_info->max_column = 2;
netsnmp_register_table(reg, table_info);
}
void
shutdown_indexes(void)
{
unregister_mib(indexes_oid, OID_LENGTH(indexes_oid));
}
/* since you are using an old version of the agent you might wish to
* add this function
*/
void deinit_indexes(void) { shutdown_indexes(); }
