Description
Enumerator-based IO
- enumHandle :: Integer -> Handle -> Enumerator SomeException ByteString IO b
- enumFile :: FilePath -> Enumerator SomeException ByteString IO b
- iterFile :: FilePath -> Iteratee SomeException ByteString IO ()
- iterHandle :: Handle -> Iteratee SomeException ByteString IO ()

Arguments
| :: Integer | Buffer size |
| -> Handle | |
| -> Enumerator SomeException ByteString IO b |
Read bytes (in chunks of the given buffer size) from the handle, and
stream them to an Iteratee. If an exception occurs during file IO,
enumeration will stop and Error will be returned. Exceptions from the
iteratee are not caught.
This enumerator blocks until at least one byte is available from the handle, and might read less than the maximum buffer size in some cases.
enumFile :: FilePath -> Enumerator SomeException ByteString IO bSource
Opens a file path in binary mode, and passes the handle to enumHandle.
The file will be closed when the Iteratee finishes.
iterFile :: FilePath -> Iteratee SomeException ByteString IO ()Source
Opens a file path in binary mode, and passes the handle to iterHandle.
The file will be closed when the Iteratee finishes.
iterHandle :: Handle -> Iteratee SomeException ByteString IO ()Source
Read bytes from a stream and write them to a handle. If an exception
occurs during file IO, enumeration will stop and Error will be
returned.
