Is there any way to create a handle which dumps its input into a string or memory buffer of some kind? I only know of the ability to open file/socket handles, and a quick browse of GHC/Handle.hs doesn't seem to indicate anything else. I'm not counting createPipe/fdToHandle because that is not portable. -- -- Matthew Danish -- user: mrd domain: cmu.edu -- OpenPGP public key: C24B6010 on keyring.debian.org _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
