[Haskell-beginners] Named Pipes Et Cetera

[matthew coolbeth]

Hello, all.

Three questions:

1> What, if anything, can I do in a Haskell program to do blocking
reads from a Linux FIFO?  For the curious, there is a small program
below that doesn't block, but immediately terminates because of an EOF

2> How could I have found the answer to this question on my own? (The
documentation that Google found for me was not completely adequate)

3> Is this sort of question generally regarded as too unixy or not
haskelly enough to be appropriate for this mailing list?

Thanks.

main = do
        createNamedPipe pipeString $ unionFileModes ownerReadMode ownerWriteMode
        pipe <- openFile pipeString ReadMode
        forever (hGetLine pipe >>= putStrLn)
