[Caml-list] Unix.create_process

["Rolf Wester" <wester@ilt.fhg.de>]

Hi,

I want to start a process and read the stdout channel of this process.
I tried:

let instring = String.create 10 in
    let pid = Unix.create_process ~prog:"ls" ~args:[|"/usr"|] 
			~stdin:Unix.stdin ~stdout:Unix.stdin ~stderr:Unix.stderr in
    let nread = Unix.read Unix.stdin ~buf:instring ~pos:0 ~len:10 in instring;;

but this one waits for keyboeard input instead of reading the output of ls.
When I type  ~stdout:Unix.stdout instead of  ~stdout:Unix.stdin the ls 
output is written to stdout (as expected).

Can anybody tell me what I made wrong?

Thanks in advance.
