openBinaryFile :: OsPath -> IOMode -> IO Handle

Like openFile, but open the file in binary mode. On Windows, reading a file in text mode (which is the default) will translate CRLF to LF, and writing will translate LF to CRLF. This is usually what you want with text files. With binary files this is undesirable; also, as usual under Microsoft operating systems, text mode treats control-Z as EOF. Binary mode turns off all special treatment of end-of-line and end-of-file characters. (See also hSetBinaryMode.)

withFile :: OsPath -> IOMode -> (Handle -> IO r) -> IO r

Run an action on a file.

The Handle is automatically closed afther the action.

withBinaryFile :: OsPath -> IOMode -> (Handle -> IO r) -> IO r

withFile' :: OsPath -> IOMode -> (Handle -> IO r) -> IO r

Run an action on a file.

The Handle is not automatically closed to allow lazy IO. Use this with caution.

withBinaryFile' :: OsPath -> IOMode -> (Handle -> IO r) -> IO r

readFile :: OsPath -> IO ByteString

The readFile function reads a file and returns the contents of the file as a ByteString. The file is read lazily, on demand.

readFile' :: OsPath -> IO ByteString

The readFile' function reads a file and returns the contents of the file as a ByteString. The file is fully read before being returned.

writeFile :: OsPath -> ByteString -> IO ()

The computation writeFile file str function writes the lazy ByteString str, to the file file.

writeFile' :: OsPath -> ByteString -> IO ()

The computation writeFile file str function writes the strict ByteString str, to the file file.

appendFile :: OsPath -> ByteString -> IO ()

The computation appendFile file str function appends the lazy ByteString str, to the file file.

appendFile' :: OsPath -> ByteString -> IO ()

The computation appendFile file str function appends the strict ByteString str, to the file file.

openFile :: OsPath -> IOMode -> IO Handle

Open a file and return the Handle.

openExistingFile :: OsPath -> IOMode -> IO Handle

Open an existing file and return the Handle.
