Hi all,
I have a MIB that defines 3 tabular fields that must be processed as a
cohesive unit of data. For example IP, netmask, default gateway.
I am using net-snmp v5.2.4 and my tables use the iterate-access style of
coding.
I want to access the three vbs from a single request and set them to
"already processed" so they are not checked for validity again.
I am going to leave the set logic alone and each var can be set
individually, they are just checked as a group.
Clearly I could do nothing special and check the group 3 times, but I am
trying to be somewhat efficient.
I have been analyzing the data structures for
netsnmp_request_info *request;
netsnmp_table_request_info *table_info;
netsnmp_variable_list *var;
The request data structure is all the incoming data given to the
processing handler. It seems to be a list of requests, each with
different lists of varbinds (although mostly common to each other). I
see that each varbind in the request in a multivarbind check or set is
listed under request->requestvb and that each subsequent request in the
submitted list removes a vb from the head of the requestvb list as the
check or set is processed. I first thought the request->processed flag
would do the trick but subsequent requests in the list could contain the
vbs I need to look at.
I also see the var->data and var->dataFreeHook() in the varbind
structure, I could use this to save some state info (like a boolean ==
TRUE) to prevent rechecking, and free it when the check routines are
complete.
My question is. Is there a better way to do this that fits in with the
architecture? Is there a way to set a vb as checked that is built in?
Thanks in advance,
Adam
