Documentation

init :: [InitFlag] -> IO ()

Initializes SDL. This should be called before all other SDL functions.

withInit :: [InitFlag] -> IO a -> IO a

initSubSystem :: [InitFlag] -> IO ()

After SDL has been initialized with SDL_Init you may initialize uninitialized subsystems with SDL_InitSubSystem.

quitSubSystem :: [InitFlag] -> IO ()

quit :: IO ()

wasInit :: [InitFlag] -> IO [InitFlag]

wasInit allows you to see which SDL subsytems have been initialized

getError :: IO (Maybe String)

Returns a string containing the last error. Nothing if no error.

failWithError :: String -> IO a

unwrapBool :: String -> IO Bool -> IO ()

unwrapMaybe :: String -> IO (Maybe a) -> IO a

unwrapInt :: (Int -> Bool) -> String -> IO Int -> IO Int
