SDL_HINT_POLL_SENTINEL - Man Page

#include <SDL3/SDL_hints.h>

#define SDL_HINT_POLL_SENTINEL "SDL_POLL_SENTINEL"

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.

This hint is available since SDL 3.2.0.
