Hi all, I have two handles where I get stdout resp. stderr from a command output.

Is it possible to merge those two handles so that I get a new input handle in a way that data can be read from the new handle whenever it is available from either of the two original handles?

Does what you're doing strictly need to be a handle?

One thing you could try is is using an IO Channel: http://hackage.haskell.org/packages/archive/base/latest/doc/html/Control-Con...

Hmm, not quite sure. I was asking about handles because I use: (_ ,Just hout ,Just herr ,p) <- createProcess (proc cmd parms) { std_out = CreatePipe, std_err = CreatePipe } which gives me handles to deal with. -- Manfred
