array 
snmpwalk ( string hostname, string community, string object_id [, int timeout [, int retries]] )
     Returns an array of SNMP object values starting from the
     object_id as root and FALSE on error.
    
 
     snmpwalk() function is used to read all the
     values from an SNMP agent specified by the
     hostname. Community
     specifies the read community for that agent. A NULL
     object_id is taken as the root of the SNMP
     objects tree and all objects under that tree are returned as an
     array. If object_id is specified, all the
     SNMP objects below that object_id are
     returned.
     
    
     Above function call would return all the SNMP objects from the
     SNMP agent running on localhost. One can step through the values
     with a loop
