NAME

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

SYNOPSIS

       #include <SDL3/SDL_hints.h>

       #define SDL_HINT_POLL_SENTINEL "SDL_POLL_SENTINEL"

DESCRIPTION

       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.

AVAILABILITY

       This hint is available since SDL 3.2.0.
