Why we use poll event function?

Question

What is poll event function and why we use it in game loop/main loop in SFML?

Answer 1

Because the events get queued up internally and by calling pollEvent you'll get the top event of the queue

Answer 2

So we don't want to use this while we have only one event?🤔

Can we see the events that lined in the queues? 😅
