Subject: [Caml-list] Child process doesn't terminate
Date: Mon, 24 Mar 2014 19:23:05 +0100 [thread overview]
Message-ID: <53307809.80202@ens-cachan.org> (raw)
Hi,
In the following program, the child process "cat" never terminates. I
don't understand why; can anyone tell me?
~~~
let _ =
let open Unix in
let indescr, outdescr = pipe () in
let outchan = out_channel_of_descr outdescr in
let pid =
create_process "/bin/cat" [|"cat"|]
indescr stdout stderr
in
Printf.fprintf outchan "Hello!\n%!";
close indescr;
close outdescr;
ignore (waitpid [] pid) (* stuck here *)
~~~
