SDL_PollEvent
Name
SDL_PollEvent -- Polls for currently pending events.
Synopsis
#include "SDL.h" int SDL_PollEvent(SDL_Event *event);
Description
Polls for currently pending events.
If event is not NULL, the next event is removed from the queue and stored in the SDL_Event structure pointed to by event.
As this function implicitly calls SDL_PumpEvents, you can only call this function in the thread that set the video mode.
Return Value
Returns 1 if there are any pending events, or 0 if there are none available.
