Subject: Unix.create_process vs Unix.open_process_out
Date: Mon, 14 Apr 2008 08:43:14 -0400 [thread overview]

Consider the following two functions:
let test1 () =
let w = Unix.open_process_out "cat" in
assert (Unix.close_process_out w = Unix.WEXITED 0)
let test2 () =
let r,w = Unix.pipe () in
let pid = Unix.create_process "cat" [| "cat" |] r Unix.stdout
Unix.stderr in
Unix.close w;
assert (snd (Unix.waitpid [] pid) = Unix.WEXITED 0)
Both execute "cat" and then close its stdin immediately. This should cause
cat to terminate. In test1 this works as expected but in test2, cat keeps
running forever. Is this the expected behavior of Unix.create_process?
