[Haskell-cafe] trying to use unix's openFD ..

[Galchin Vasili]

Hello,

       The signature for openFD is

openFd: FilePath
            -> OpenMode
            -> Maybe FileMode
            -> OpenFileFlags
            -> IO Fd

I am currently reading
http://www.haskell.org/ghc/docs/latest/html/libraries/unix/System-Posix-Files.html
and diving down into links but can't find the definition of data type
FileMode. ??? Basically I want to open in O_RDONLY filemode.

Kind regards, Vasili
