Ah, I see what you meant. Well, in this case, Lite Foundation offers you something like "this".
Here would be the example using LF, assuming that there is a class named foo:
void sayHello(foo *this, int num)
{
printf("Hello world");
this->num = num;
}
foo *bar = createFooInstance();
sayHello(bar, 10);
It works basically the same way, but without the need of a invoke function. However, LF also has a invoke function which is used in cases where polymorphism is needed (protocols), but the functions also pass the receiving object ("this") as the first parameter to functions.
