Hmmm....
That's a slightly unusual approach, but it should work OK.
But hardcoding the name of the config file isn't sensible as a
general solution (though it's fair enough while testing).
You'd probably be better off using the "standard" persistent config file.
Either calculate this using something like
sprintf(config_file, "%s/%s.conf", get_persistent_directory(),
netsnmp_ds_get_string(NETSNMP_DS_LIBRARY_ID,
NETSNMP_DS_LIB_APPTYPE));
or (better) use the API routine
read_app_config_store()
to save each line.
This can either be done directly, or (better) linked into the
automatic shutdown mechanism:
snmp_register_callback(SNMP_CALLBACK_LIBRARY,
SNMP_CALLBACK_STORE_DATA,
store_from_database, NULL);
(where 'store_from_database' is the routine to save the config lines).
There are a number of examples of this in the current agent - look
for where the SNMP_CALLBACK_STORE_DATA callback is registered.
