I'not sure of what you want, but does this do the job?
let système command f_line = 
  let cin = Unix.open_process_in command
  in 
    (try while true do
      f_line (input_line cin);
    done with | End_of_file -> ());
  Unix.close_process_in cin
;;
It is just a function that give to 'f_line' evry 
lines produced by a pipe by the 'command'.

I use it for Xdialog2Ocaml

Kevin.
