Re: table generated by mib2c.iterate with timeout

[Jordan Janeiro Lopes da Silva]

I'm not updating loop_context. I've filled with a constant to test while
querying the agent. This is my code.

get_first
{
    netsnmp_variable_list *vptr;

    *my_loop_context = NULL /* XXX */;
    *my_data_context = NULL /* XXX */;

    vptr = put_index_data;
    
    snmp_set_var_value(vptr, (u_char *) "TEST"/* XXX: gpsMonitorID data */,  
  strlen("TEST")/* XXX: length of gpsMonitorID data */);
    vptr = vptr->next_variable;
    
    return put_index_data;
}

get_next
{
    netsnmp_variable_list *vptr;

    *my_loop_context = NULL /* XXX */;
    *my_data_context = NULL /* XXX */;

    vptr = put_index_data;
    
    snmp_set_var_value(vptr, (u_char *) "TEST1"/* XXX: gpsMonitorID data */, 
   strlen("TEST1")/* XXX: length of gpsMonitorID data */);
    vptr = vptr->next_variable;
    
    //return put_index_data;
    return NULL;
}

When I query the table with the index TEST, the result comes to me. When I
query with another index, I got this message: "No Such Instance currently
exists at this OID."
