[Haskell-cafe] Creating pseudo terminals

How can I create a pseudo terminal in Linux with Haskell? Nothing is jumping out at me in the standard library. I haven't done this before in any language, so any tips would be appreciated. From what I gather, a call to posix_openpt or openpty returns a master and a slave, or alternatively opening /dev/ptmx followed by calls to grantpt and unlockpt. I'm building a load balancing and sharing system similar to Platform's LSF. The pseudo terminal is for interactive jobs running on a remote machine. Thanks for any help! -Tom
