I want that we agree some minimal set of methods for IO channles, and agree to accept such an IO channel as an argument for our library functions, or provide a converter to a native IO channel of the library. For a polymorphic channel, minimal class types would be (for input) ['a] object get : unit -> 'a end (raise End_of_file when there is no more element to read.) (for output) ['a] object put : 'a -> unit flush : unit -> unit close : unit -> unit end for a character channel, (for input) object input : string -> int -> int -> int end ([c#input s pos len] fills s from pos with less than [len] characters, and returns the number of characters really filled.) (for output) object output : string -> int -> int -> unit flush : unit -> unit close : unit -> unit end ([c#output s pos len] outputs [len] characters from the position [pos]) I'm interested in your opinion (and of all caml list participants). -- Yamagata Yoriyuki ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
