[Haskell-beginners] System.IO.withFile

19 Jan 2009

      Hi folks,

I am trying to use the withFile function of System.IO, but it always return
an empty string when testing.

Could someone explain why:

main= do
              h<-openFile "test.cir" ReadMode
              c<-hGetContents h
              print c
...
runhaskell test1.hs
"* Teste\n\nR1  1 0 10\nC1  1 0 10uF\nI1  1 0 1mA\n\n.DC \n.PRINT\n"
works and

main= (withFile "test.cir" ReadMode hGetContents) >>= print
...
runhaskell test1.hs
""
don't?

Thanks!
