SDL_Quit

Clean up all initialized subsystems.

Syntax

void SDL_Quit(void);

Remarks

You should call this function even if you have already shutdown each initialized subsystem with SDL_QuitSubSystem(). It is safe to call this function even in the case of errors in initialization.

If you start a subsystem using a call to that subsystem's init function (for example SDL_VideoInit()) instead of SDL_Init() or SDL_InitSubSystem(), then you must use that subsystem's quit function (SDL_VideoQuit()) to shut it down before calling SDL_Quit(). But generally, you should not be using those functions directly anyhow; use SDL_Init() instead.

You can use this function with atexit() to ensure that it is run when your application is shutdown, but it is not wise to do this from a library or other dynamically loaded code.

Code Examples

#include "SDL.h"
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char** argv) {
    if (SDL_Init(SDL_INIT_EVERYTHING) != 0) {
        fprintf(stderr, "Unable to initialize SDL:  %s\n", SDL_GetError());
        return 1;
    }
    atexit(SDL_Quit);

    /* ... */

    return 0;
}
