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.

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.
