SDL_QuitSubSystem

Name

SDL_QuitSubSystem -- Shut down requested initialized subsystems

Synopsis

#include <SDL.h>

void SDL_QuitSubSystem (Uint32 flags);

Description

SDL_QuitSubSystem shuts down one or more SDL subsystems, specified by flags, earlier started by SDL_Init or SDL_InitSubSystem.

You might want to do this to save memory if your program only needs a certain subsystem some of the time.

This function uses the same SDL_INIT_* values as SDL_Init, except that SDL_INIT_NOPARACHUTE and SDL_INIT_EVENTTHREAD do nothing.

Return Value

Returns nothing.

Note: 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.

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

Example

   1 #include <SDL.h>
   2 
   3 /* ... */
   4 
   5 int main(int argc, char **argv) {
   6     int sdl_initialized = 0;
   7     sdl_initialized = !SDL_Init(0);
   8 
   9     /* ... console stuff ... */
  10 
  11     if (sdl_initialized && SDL_InitSubSystem(SDL_INIT_VIDEO)) {
  12         display_graph();
  13         SDL_QuitSubSystem(SDL_INIT_VIDEO);
  14     }
  15 
  16     /* ... more console stuff ... */
  17 
  18     if (sdl_initialized) SDL_Quit();
  19     return 0;
  20 }
