with snmpget api, the agent returns the value associated 

with the OID (or OIDs) specified in the original request.

The snmpgetnext api is  similar, but the agent returns the 

value associated with the next (valid) OID



eg:

snmpgetnext('192.168.40.134',

                   'public',

                   'SNMPv2-MIB::sysUpTime.0');



will give the output:

STRING: user@hostname
