Haskell: hIsSeekable: Check whether handle is seekable (or) not

hIsSeekable function takes a handle and return IO True, if the handle is seekable, else IO False. Not all handles are seekable, for example, a handle associated with socket is not seekable.

Prelude System.IO> :t hIsSeekable

hIsSeekable :: Handle -> IO Bool

import System.IO

        putStrLn "Enter file name (Including full path) to read"

        fileHandle <- openFile fileName ReadMode

        isSeekable <- hIsSeekable fileHandle

        putStrLn $ "Is file handle seekable " ++ show isSeekable
