SDL_HINT_POLL_SENTINEL - A variable controlling the use of a sentinel event when polling the event queue.

       This hint is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                          SDL_HINT_POLL_SENTINEL(3)

       When polling for events, SDL_PumpEvents
        is  used  to  gather  new  events  from devices. If a device keeps producing new events between calls to
       SDL_PumpEvents , a poll loop will become stuck until the new events stop. This is  most  noticeable  when
       moving a high frequency mouse.

       The variable can be set to the following values:

       • "0": Disable poll sentinels.

       • "1": Enable poll sentinels. (default)

       This hint can be set anytime.
