failIf :: (a -> Bool) -> String -> IO a -> IO aSource

failIf_ :: (a -> Bool) -> String -> IO a -> IO ()Source

failIfNull :: String -> IO (Ptr a) -> IO (Ptr a)Source

failIfZero :: Num a => String -> IO a -> IO aSource

nullPtr :: Ptr aSource

The constant nullPtr contains a distinguished value of Ptr that is not associated with a valid memory location.
