A tutorial’s code from LazyFoo fantastic place’s 01_hello_SDL web page does not present a white type, however a desktop’s display, like a screenshot. Something like:

The code:

//Using SDL and normal IO
#embody <SDL2/SDL.h>
#embody <stdio.h>

//Screen dimension constants
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;

int essential( int argc, char* args[] )
{
    //The window we'll be rendering to
    SDL_Window* window = NULL;

    //The floor contained by the window
    SDL_Surface* screenSurface = NULL;

    //Initialize SDL
    if( SDL_Init( SDL_INIT_VIDEO ) < 0 )
    {
        printf( "SDL couldn't initialize! SDL_Error: %sn", SDL_GetError() );
    }
    else
    {
        //Create window
        window = SDL_CreateWindow( "SDL Tutorial", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN );
        if( window == NULL )
        {
            printf( "Window couldn't be created! SDL_Error: %sn", SDL_GetError() );
        }
        else
        {
            //Get window floor
            screenSurface = SDL_GetWindowFloor( window );

            //Fill the floor white
            SDL_FillRect( screenSurface, NULL, SDL_MapRGB( screenSurface->format, 0xFF, 0xFF, 0xFF ) );

            //Update the floor
            SDL_UpdateWindowFloor( window );

            //Wait two seconds
            SDL_Delay( 2000 );
        }
    }

    //Destroy window
    SDL_DestroyWindow( window );

    //Quit SDL subsystems
    SDL_Quit();

    return 0;
}

Putting PumpEvents(); or whereas(SDL_PollEvent(&occasion))... did not work, sadly.
