(This is the legacy documentation for stable SDL2, the current stable version; SDL3 is the current development version.)


Shut down specific SDL subsystems.


void SDL_QuitSubSystem(Uint32 flags);

Function Parameters

flags 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().


This function is available since SDL 2.0.0.
