Documentation
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
getError :: IO (Maybe String) Source #
Returns a string containing the last error. Nothing if no error.
failWithError :: String -> IO a Source #
