Re: How to enumerate a Lua table in C++?

[Gopalakrishnan Subramani <gopalakrishnan.subramani@...>]

Thanks for example. I feel difficult to understand the enumeration. Based on a example, I could iterate a table in Lua.

Does LuaBind help to iterate much easier?

Here the senario:

function get_table()
   return { {1, 2, 3} }
end

I need to call the function and enumerate the value. Please help me.

Regards,

Krish

Use lua_next, which is described quite well in the C API
documentation.  Start with a nil key, then keep retrieving the next
element from the table until you get another nil back which means
you're done.
