Re: [Haskell-cafe] Replacing stdin from within Haskell

Thanks That is what I thought. I'll stick with what I'm doing at present which is to use temporary files - don't want to get into separate processes which I then have to co-ordinate. Cheers Neil On 9 Jun 2011, at 17:01, Brandon Allbery wrote:

Anyone out there got an elegant solution to being able to fork a haskell thread and replace its 'stdin' ?

File descriptors/file handles are per process, not per thread, on (almost?) every OS ghc supports. You'll need to create a full subprocess.
