Advice/example on how to do snmp walk

[opensourcegeek]

I'm trying to do a SNMP walk using getnext but I'm not too sure how to make it keep running until it hits end of the sub-tree. Even some pseudo-code will be really helpful.

Probably too late to answer now, but what about something along these lines(very pseudo-ish)?

last_oid = tree;

loop {
    response = getnext(last_oid);
    
    if last_oid is prefix of tree {
        do_stuff_with(response);
        last_oid = response.varbinds.last();
    } else {
        break;
    }
}
