Hi,
root and rootlen are defined as below :
oid root[MAX_OID_LEN];
int rootlen = MAX_OID_LEN;
Btw, I've figured out the problem. The OID types works fine in other
tables but in this particular table i had some empty columns. With
strings they just return nulls "". With OID types snmpwalk can't find
the next value and timeouts.
What actually happens when snmp_parse_oid parses an empty string?
Temporarily in the agent I'm returning "1.3.6.1.4.1" if string is NULL
just so the agent has something to parse.
Thanks in advance,
Syikin

How are you defining the variable 'root'?
What value does 'rootlen' have before you call this routine?
Remember that you need to initialise rootlen with the size of the
buffer - i.e. the maximum size of the OID that can be handled.
The value returned will be the *actual* size of the OID that was
parsed.
If you're re-using this length variable for parsing two or more
OID strings, then you need to re-set the length to indicate the
maximum size before trying to parse the second one.
