I can pass a list of args to runProcess.. fine. So I can use runProcess ... (Just stdin) (Just stdout) ... to borrow the handles ? No: the comments say: -- Any 'Handle's passed to 'runProcess' are placed immediately in the closed state. That's not what I want.
So I think there is still a function missing ? Cale has pointed me to hsh so I'll have a look there..
Perhaps you just want to pass Nothing for the "Maybe Handle" arguments to runProcess, which means "inherit from the parent process"? Cheers, Simon
