Specifically, I'd like to use "pipe" from the Posix library to create a pipe and then pass one end of it to runProcess as its stdin.
You may want to take a look at POpen (available from hslibs cvs, or http://www.01.246.ne.jp/~juhp/haskell/popenhs/). Process output works well, though it still has some problems with lazy process input.
I have had problems with pipes and runProcess, now I am using forkProcess/executeFile/getProcessStatus and it works properly.
Non-lazy IO presumably? Do you have an example you can show? Jens
