A TValue pointer. That is the universal, internal variable value holding 
structure.

You get it by:

TValue *o = XLUA_INDEX_TO_ADDRESS(L, index);

See: http://hdiedrich.github.com/darc/README.html

int word_filter(TValue *variable, void *state)
{
    /* if a string: ... */
   if(XLUA_IS_STRING(variable))

       /* screen it */
       return inspect(XLUA_STRING(variable));

   /* if a table: ... */
   else if(XLUA_IS_TABLE(variable))

       /* traverse table, using this function as callback, for each 
element */
       return darc_traverse(XLUA_TABLE(variable), word_filter, state);

   return 1;
}
