(* Module [ThreadUnix]: thread-compatible system calls *)

(* This module is deprecated: its functionality has been merged back into
   the [Unix] module.  Threaded programs can now call the functions
   from module [Unix] directly, and still get the correct behavior
   (block the calling thread, if required, but do not block all threads
   in the process).  *)

(*** Process handling *)

val execv : string -> string array -> unit
val execve : string -> string array -> string array -> unit
val execvp : string -> string array -> unit
val wait : unit -> int * Unix.process_status
val waitpid : Unix.wait_flag list -> int -> int * Unix.process_status
val system : string -> Unix.process_status

(*** Basic input/output *)

val read : Unix.file_descr -> string -> int -> int -> int
val write : Unix.file_descr -> string -> int -> int -> int

(*** Input/output with timeout *)

val timed_read :
      Unix.file_descr ->
      string -> int -> int -> float -> int
val timed_write :
      Unix.file_descr ->
      string -> int -> int -> float -> int
      (* Behave as [read] and [write], except that
         [Unix_error(ETIMEDOUT,_,_)] is raised if no data is
         available for reading or ready for writing after [d] seconds.
         The delay [d] is given in the fifth argument, in seconds. *)

(*** Polling *)
