Re: snmp_parse_oid

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
