Can I make multiple Lua VMs in one thread?

Question

As I know, I can create a Lua VM for each thread. But I'm not sure about multiple instances in the stream. Is it possible?

Answer 1

You can create multiple states, but without threads or multiple processes, you can only run one of them at a time. In addition, you cannot communicate between states in the Lua core, so you need to either write your own or find a library to perform any synchronization or interstate communication.

Answer 2

Yes, you can just call the create function several times.

Answer 3

comparing two references to objects using the operator == to true only if both references to the same object.
