Initialization & Shutdown (SDL.h)

Initialization & Shutdown (SDL.h)

Initialization
To begin using SDL in your program SDL_Init() must be called to initialize subsystems and enable use of other SDL functions.

• The Event Handling, File I/O, and Threading subsystems are initialized by default. To initialize other subsystems you must specifically call them. Multiple subsystems may be or'd together.

• Example:

  • SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO);

  • Initializes the 3 default subsystems plus the Video and Audio subsystems.

Shut Down
SDL_Quit() should be called before an SDL application exits to shut down all subsystems, including the default ones.

• It is not necessary to specify individual subsystems when using SDL_Quit(). It will automatically shut down all active subsystems.
