SDL Wiki


Shut down specific SDL subsystems.


void SDL_QuitSubSystem(Uint32 flags);

Function Parameters


any of the flags used by SDL_Init(); see SDL_Init for details.


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(), SDL_QuitSubSystem() and SDL_WasInit() will not work. You will need to use that subsystem's quit function (SDL_VideoQuit()) directly instead. But generally, you should not be using those functions directly anyhow; use SDL_Init() instead.

You still need to call SDL_Quit() even if you close all open subsystems with SDL_QuitSubSystem().

Code Examples

#include "SDL.h"

/* ... */

int main(int argc, char **argv) {
    int sdl_initialized = 0;
    sdl_initialized = !SDL_Init(0);

    /* ... console stuff ... */

    if (sdl_initialized && SDL_InitSubSystem(SDL_INIT_VIDEO)) {

    /* ... more console stuff ... */

    if (sdl_initialized) SDL_Quit();
    return 0;
