I am trying to simulate an SDL keyboard button press (using C). I have looked up the SDL info pages online but I still don't have anything that consistently works.

I have the following (removed the interrupt handling, creation of windows etc.)

while(1){
    SDL_Event user_event;
    user_event.type = SDL_SCANCODE_LEFT;

    SDL_PushEvent(&user_event);
    SDL_PumpEvents();

    const Uint8 *state = SDL_GetKeyboardState(NULL);

    if (state[SDL_SCANCODE_LEFT]) {
        printf("LEFT PRESSED");
    }
    if (state[SDL_SCANCODE_RIGHT]) {
        printf("RIGHT PRESSED");
    }
}

I never see the 'LEFT PRESSED' string printed out, although when I press the right arrow key (from keyboard) I see the respective output generated. It appears like the left key press is never being pushed on the state var.

Any help would be greatly appreciated.
