    *)
val strerror : error -> string

error message for the given error code

val err_name : error -> string

error name for the given error code

val to_unix_error : error -> Unix.error

map error to Unix.error , Unix.EUNKNOWNERR is used, if the mapping is not possible

val of_unix_error : Unix.error -> error

get back the original Uwt.error from an exception raised by a Uwt function

type 'a uv_result = ('a, error) Stdlib.result
type ('a, 'b) o_result = ('a, 'b) Stdlib.result =
  1. | Ok of 'a
  2. | Error of 'b

Please use Result.Ok or just Ok, not Uwt.Ok or Uwt_base.Ok

  • deprecated please use Result.result instead
type 'a result = ('a, error) o_result
  • deprecated please use Result.result or uv_result instead
module Int_result : sig ... end

Int_result.t is used instead of 'a result, if a function returns either an error or a non-negative integer (including unit/bool).

type file

Abstract type for a file descriptor. Unlike Unix.file_descr it is not intended to wrap a SOCKET.

type sockaddr = Unix.sockaddr
type buf = (char, Bigarray.int8_unsigned_elt, Bigarray.c_layout) Bigarray.Array1.t
val stdin : file

File descriptor for standard input.

val stdout : file

File descriptor for standard output.

val stderr : file

File descriptor for standard error.

module Iovec_write : sig ... end

pass multiple buffers at once to a libuv write function.

module Fs_types : sig ... end
module type Fs_functions = sig ... end
module Conv : sig ... end
module Misc : sig ... end

This section contains miscellaneous functions that don't really belong in any other section.

module Sys_info : sig ... end

Information about your operating system.
