SDL is a cross-platform multi-media library written in C. It provides low-level access interfaces for audio, video, keyboard, mouse, control bar, and 3D hardware through OpenGL and Direct3D. It is widely used in MPEG playback software, simulators, and many games, including the Linux version that won the grand prize "Civilization: Power call.

#include "SDL.h"int main(int argc, char* argv[]){        SDL_Window* window;        SDL_Renderer* renderer;        // Initialize SDL.        if (SDL_Init(SDL_INIT_VIDEO) < 0)                return 1;        // Create the window where we will draw.        window = SDL_CreateWindow("SDL_RenderClear",                        SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,                        512, 512,                        0);        // We must call SDL_CreateRenderer in order for draw calls to affect this window.        renderer = SDL_CreateRenderer(window, -1, 0);        // Select the color for drawing. It is set to red here.        SDL_SetRenderDrawColor(renderer, 255, 0, 0, 255);        // Clear the entire screen to our selected color.

SDL_RenderPresent(renderer);        // Give us time to see the window.        SDL_Delay(5000);        // Always be sure to clean up        SDL_Quit();        return 0;}
