init :: [InitFlag] -> IO ()Source
Initializes SDL. This should be called before all other SDL functions.
initSubSystem :: [InitFlag] -> IO ()Source
After SDL has been initialized with SDL_Init you may initialize uninitialized subsystems with SDL_InitSubSystem.
quitSubSystem :: [InitFlag] -> IO ()Source
wasInit :: [InitFlag] -> IO [InitFlag]Source
wasInit allows you to see which SDL subsytems have been initialized
failWithError :: String -> IO aSource
