Passing arrays from C++ to LUA

[<Andreas.Volz@...>]

Hello,

I like to pass some C++ arrays to LUA. The other way from LUA to C++ is already done. I show you in pseudo language what I need:

LUA:
> a = getArray ()

C++:
fill a array with many numbers and return it in the getArray() function

LUA:
> print (a[1])
4
> print (a[2])
5
> print (a[3])
6
....

My problem is I don't know how to do this in C++. Perhaps someone could help and tell me how this works. What I tried last was:

C++:
    lua_newtable (L);
    lua_settable (L,1);
    
    lua_Integer n = 6;
    lua_pushinteger (L, n);

LUA:
	tc=TestClass:new()
	a=tc:testX()
	print (a[1])
	[string "print (a[1])"]:1: attempt to index global 'a' (a nil value)


regards

	Andreas Volz
