I can create a new Thread object and get a unique id string for it, but how can I get the currently running thread or its unique id string? Or equally useful for my purposes, how can I test if the currently running thread == a particular Thread that I've created?

I'm asking because I believe I can implement a particular function in a thread-safe way without locks, but only if I can evaluate what thread is calling the function.

There is an OS.set_thread_name(), but no get_thread_name(). I guess this is the string that I would get if I used Thread.get_id(), but haven't tested this. In any case, I don't want to change any thread names, just look at them from running code.

Maybe you can save the thread id in the function itself.

func _button2_pressed(thread):
    var thid=thread.get_id()

func _on_Button_pressed():
    var thread=Thread.new()
    var id=thread.start (self, "_button2_pressed", thread)

    var thread1=Thread.new()
    var id1=thread1.start (self, "_button2_pressed", thread1)

Thanks! This will work if there really isn't a more direct way.
