Re: [Caml-list] OCaml-ssl and input_string

Hello,
Well, I don't know how it should work, but from what I've seen, it
seems that its read function will wait untill there is something to
read if nothing is available.

Anyway, I have written an input_line (read character by character
untill a '\n') function which allows me to stop as soon as I can match
the begining of the line read with a pattern I get on the greeting.
That will work untill someone tries to send me funny mails with lots
of line feeds followed by weird 8-10 characters strings followed by a
space, I guess it's safe enough.

I just don't feel confident writing things such as :

  let ret = Buffer.create 1024 in
  let str = ref (input_line s) in
  while try Scanf.sscanf !str (Scanf.format_from_string (id^ " ")  "")
(fun _ -> ()) (); false with _-> true do
    Buffer.add_string ret !str;
    str:=input_line s
  done;
  Buffer.contents ret
