You could also use the datalist in the agent request info (which is shared for all varbinds in a request), instead of saving the pointer for each varbind in a request. Either way, make sure you pass a free routine to release the memory. If you are using the parent_data in each request, make sure you handle multiple requests (eg if they both have the same pointer, use reference counting so you don't delete twice or delete before the second request references the pointer). If you are using the agent request info, make sure you use a unique key name per group, or a pdu with a varbind in two different groups will confuse things. -- Robert Story; NET-SNMP Junkie Support: <http://www.net-snmp.org/> <irc://irc.freenode.net/#net-snmp> Archive: <http://sourceforge.net/mailarchive/forum.php?forum=net-snmp-users> You are lost in a twisty maze of little standards, all different. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
