- Subject: Passing arrays from C++ to LUA

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
