withHandle :: String -> Handle -> (Handle__ -> IO (Handle__, a)) -> IO a Source

withHandle' :: String -> Handle -> MVar Handle__ -> (Handle__ -> IO (Handle__, a)) -> IO a Source

withHandle_ :: String -> Handle -> (Handle__ -> IO a) -> IO a Source

withHandle__' :: String -> Handle -> MVar Handle__ -> (Handle__ -> IO Handle__) -> IO () Source

mkHandle :: (IODevice dev, BufferedIO dev, Typeable dev) => dev -> FilePath -> HandleType -> Bool -> Maybe TextEncoding -> NewlineMode -> Maybe HandleFinalizer -> Maybe (MVar Handle__) -> IO Handle Source

mkFileHandle Source

makes a new Handle

mkDuplexHandle :: (IODevice dev, BufferedIO dev, Typeable dev) => dev -> FilePath -> Maybe TextEncoding -> NewlineMode -> IO Handle Source

like mkFileHandle, except that a Handle is created with two independent buffers, one for reading and one for writing. Used for full-duplex streams, such as network sockets.

openTextEncoding :: Maybe TextEncoding -> HandleType -> (forall es ds. Maybe (TextEncoder es) -> Maybe (TextDecoder ds) -> IO a) -> IO a Source

closeTextCodecs :: Handle__ -> IO () Source

initBufferState :: HandleType -> BufferState Source

dEFAULT_CHAR_BUFFER_SIZE :: Int Source

flushBuffer :: Handle__ -> IO () Source

syncs the file with the buffer, including moving the file pointer backwards in the case of a read buffer. This can fail on a non-seekable read Handle.

flushWriteBuffer :: Handle__ -> IO () Source

flushCharReadBuffer :: Handle__ -> IO () Source

flushCharBuffer :: Handle__ -> IO () Source

flushes the Char buffer only. Works on all Handles.

flushByteReadBuffer :: Handle__ -> IO () Source

flushByteWriteBuffer :: Handle__ -> IO () Source

readTextDevice :: Handle__ -> CharBuffer -> IO CharBuffer Source

writeCharBuffer :: Handle__ -> CharBuffer -> IO () Source

readTextDeviceNonBlocking :: Handle__ -> CharBuffer -> IO CharBuffer Source

decodeByteBuf :: Handle__ -> CharBuffer -> IO CharBuffer Source

augmentIOError :: IOException -> String -> Handle -> IOException Source

ioe_closedHandle :: IO a Source

ioe_semiclosedHandle :: IO a Source

ioe_EOF :: IO a Source

ioe_notReadable :: IO a Source

ioe_notWritable :: IO a Source

ioe_finalizedHandle :: FilePath -> Handle__ Source

ioe_bufsiz :: Int -> IO a Source

hClose_help :: Handle__ -> IO (Handle__, Maybe SomeException) Source

hLookAhead_ :: Handle__ -> IO Char Source

type HandleFinalizer = FilePath -> MVar Handle__ -> IO () Source

handleFinalizer :: FilePath -> MVar Handle__ -> IO () Source
