Beware, You are only storeing the *adress* of the struct in the list
so the tmp_db_table must live as longe as You plan to use the list!

if tmp_db_table is auto and You keep acessing the list after retuning
from the function where you added this entry You may later get more or
less random stack coruption. Bad, bad, bad bug....

Might be bether to use dynamicly allocated db_table?

try
   ((struct __db_table *) table2->data)->name_table

or something simular ;-)
