Apology If I resending it again.
Thanks. But what about get_first_data_point() and get_next_data_point() ?
They also need to access the tcp_head right ? vamgic is not a an argument for
these functions.
I
have one more doubt. Let's say there is two table tcpTable and
udpTable. And both has been loaded by same _load() function and _free
function.
netsnmp_inject_handler( reginfo,
netsnmp_get_cache_handler(TCP_STATS_CACHE_TIMEOUT,
tcpTable_load, tcpTable_free,
tcpTable_oid, OID_LENGTH(tcpTable_oid)));
So I do not want to create seperate cache for udp
table. Like to keep the same cache for both the table oids.
is it possible to do so ? How can I do so ?
Thanks

You shouldn't touch the 'cache' parameter - this is used by the cache helper
to decide whether/when to invoke the load/free functions.
But you could certainly use the 'vmagic' parameter to avoid the
use of a global variable. That's exactly why this parameter is there.
