Hello,
I try to replace a LUA table in C++. I do this in LUA:
tc=TestClass:new ()
a={10,11,12,13,14,15,16,17,18,19,20,21}
tc:testX (a)
print (a[1])
print (a[2])
print (a[3])
Printed from LUA:
10
11
12
What does testX()?
printf ("dump1:\n");
stackDump (L);
array2table( L, lobj );
lua_remove(L, 2);
printf ("dump2:\n");
stackDump (L);
... and...
void array2table( lua_State *L, lua_Object lobj )
{
if (lua_istable (L, lobj))
{
printf ("element is table");
int arr[4] = { 5,100,-20,0 };
lua_newtable(L); // table
for (int i=0; i<4; i++)
{
lua_pushinteger(L, i+1); // table,key
lua_pushinteger(L, arr[i]); // table,key,value
lua_settable(L,-3); // table
}
}
}
This in printed in C++:

31018498 PID:1fe001a TID:53001e stack dump end
As you could see in 'dump2' I replaced the input table with my own table. Looks good so far. But why does LUA then print "10 11 12"? I would expect "5 100 -20". How could I access the table I replace in C++?
If I don't "lua_remove(L, 2);" then the new table is after the input table. But is there any way to access this new table in LUA?

Andreas
