[Click] Help! - Logging packets to /proc

[Beyers Cronje]

Hi Praveen,

You can use read_handler. The first argument of your read handler is a
pointer to the element. As an example look at IPRouteTable element:

String
IPRouteTable::table_handler(Element *e, void *)
{
    IPRouteTable *r = static_cast<IPRouteTable*>(e);
    return r->dump_routes();
}

void
IPRouteTable::add_handlers()
{
    add_write_handler("add", add_route_handler, 0);
    add_write_handler("set", add_route_handler, (void*) 1);
    add_write_handler("remove", remove_route_handler, 0);
    add_write_handler("ctrl", ctrl_handler, 0);
    add_read_handler("table", table_handler, 0);
    set_handler("lookup", Handler::OP_READ | Handler::READ_PARAM |
Handler::ONE_HOOK, lookup_handler);
}
