Hi, I have a small question concerning the value returned in "val_len" when returning a variable of type "oid". I have been writing a small program here in C using the net-snmp library based on the examples on the net-snmp library. It makes a snmp-query for a number of data-elements, one of them being "SNMPv2-MIB::sysObjectID.0". This returns a value of the type "oid". However, I have noticed that size of the element (as found in vars->val_len) is actually 4 times the number of elements in the oid. So, a query to a cisco returns "SNMPv2-SMI::enterprises.9.1.46" (1.3.6.1.4.1.9.1.46), vars->val_len will be 36! I need the correct size as I want need to convert this to a string using snprint_objid later. Is this relation of "size = var_val_len / 4" something that is fixed and the same on all platforms? Or is there some other trick I need do to find the correct lenght of the oid returned? Cheerio! Kr.
