throwErrnoIfMinus1

throwErrnoIfMinus1 :: Num a => String -> IO a -> IO a
base Foreign.C.Error
Throw an IOError corresponding to the current value of getErrno if the IO action returns a result of -1.
throwErrnoIfMinus1_ :: Num a => String -> IO a -> IO ()
base Foreign.C.Error
as throwErrnoIfMinus1, but discards the result.
throwErrnoIfMinus1Retry :: Num a => String -> IO a -> IO a
base Foreign.C.Error
Throw an IOError corresponding to the current value of getErrno if the IO action returns a result of -1, but retries in case of an interrupted operation.
throwErrnoIfMinus1Retry_ :: Num a => String -> IO a -> IO ()
base Foreign.C.Error
as throwErrnoIfMinus1, but discards the result.
throwErrnoIfMinus1RetryMayBlock :: Num a => String -> IO a -> IO b -> IO a
base Foreign.C.Error
as throwErrnoIfMinus1Retry, but checks for operations that would block.
throwErrnoIfMinus1RetryMayBlock_ :: Num a => String -> IO a -> IO b -> IO ()
base Foreign.C.Error
as throwErrnoIfMinus1RetryMayBlock, but discards the result.
