(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_Quit

Clean up all initialized subsystems.

Header File

Defined in SDL_init.h, but apps should use #include <SDL3/SDL.h>

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.

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.

Version

This function is available since SDL 3.0.0.

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;
}
