Hello,
I wrote a simple program to read the contents of a cdrom:
module Main where
import Text.Printf
import System.IO
import System.Posix.Types
import System.Posix.IO
main = do
fd <- openFd "/dev/cdrom" ReadOnly Nothing defaultFileFlags
readCdRom fd 4096
closeFd fd
readCdRom fd byteCount = do
(buf, actualByteCount) = fdRead fd bytecount
readCdRom fd byteCount
When it executed it read thousands of 4096 blocks as I expected. It then got
a "hardware error" which I suspect was the "end of the CD", i.e. the
begininng of the "unlasered" part of the CD. Is there a better and more
graceful way to detect and handle "end of data"?
Thanks, ,Vasili
