Re: Looking for the patch for fetch_var_val()

Hi Dave,

Thank you for your prompt response. These netsnmp_query_xxx are really nice
API supported in 5.3. Unfortunately, we are using 5.2.1 and have no plan to
upgrade to 5.3.

Therefore, any suggestions on doing the equivalent to get variable and its
value in 5.2.1 would be greatly appreciated.

Thanks again.
Emi

Yes:
$ grep netsnmp_query snmplib/client.c
netsnmp_query_set_default_session( netsnmp_session *sess)
netsnmp_query_get_default_session( void )
int netsnmp_query_get(netsnmp_variable_list *list,
netsnmp_session *session)
int netsnmp_query_getnext(netsnmp_variable_list *list,
netsnmp_session *session)
int netsnmp_query_set(netsnmp_variable_list *list,
netsnmp_session *session)
int netsnmp_query_walk(netsnmp_variable_list *list,
netsnmp_session *session)


If you're doing this from within the agent, then the snmpd.conf
directive "iquerySecName" can be used to set up the internal session
for such queries. The second parameter can then be left as NULL when
calling the main query routines.
