(* As of OCaml 4.01.0 input_value and input do not quite work well
* with threads. The symptom is the following. Two threads, each
* of them blocked on a read (on different channels). One is not
* woken up even if data is available. When the other one gets data
* then the stuck one is eventually unblocked too. Unix.select with
* an unbounded wait has the same problem. *)
(* Use only the following functions on the channel *)
type thread_ic
val prepare_in_channel_for_thread_friendly_io : in_channel -> thread_ic
val thread_friendly_input_value : thread_ic -> 'a
val thread_friendly_read :
thread_ic -> string -> off:int -> len:int -> int
val thread_friendly_really_read :
thread_ic -> string -> off:int -> len:int -> unit
