>>I've got a simple question.
I'm storing into a table several items(other tables) using a numerical index
as key
and I would like to know how many elements are into the table.So I tryed
with lua_getn();
The problem is that I'm not inserting sorted elements, for instance if I
insert the first element with
key 8 getn() will return 8.
Is there any way to have the real number of "non nil" elements?
Write your own! :o)
getn returns the highest numerical key. Have a look in the manual.
