table api question

[Edgar Pettijohn]

I am writing a table-lua, however the table_lua_update function doesn't appear 
to be called.
Here are relevant pieces of the code.

The lookup function works. However, it would be more ideal to have the update() 
called early
to fill in the tables for the other functions. As is the lookup() has to do the 
work of both.

Any help is appreciated.

Thanks,

Edgar

        int ret;

        lua_getglobal(L, "update");

        if (lua_pcall(L, 1, 1, 0)) {
                log_warnx("warn: update: %s", lua_tostring(L, -1));
                return -1;
        }

        ret = lua_toboolean(L, -1);

        log_warnx("\t\tlua-update: %d\n", ret);
        return ret;
