luv 0.5.12 · OCaml Package

TCP sockets.

See TCP in the user guide and uv_tcp_t — TCP handle in libuv.

type t = [ `TCP ] Stream.t

Binds uv_tcp_t.

Note that values of this type can also be used with functions in:

In particular, see Luv.Handle.close, Luv.Stream.accept, Luv.Stream.read_start, Luv.Stream.write.

val init : 
  ?loop:Loop.t ->
  ?domain:Sockaddr.Address_family.t ->
  unit ->
  (t, Error.t) result

Allocates and initializes a TCP stream.

Binds uv_tcp_init_ex.

The stream is not yet connected or listening. See Luv.TCP.bind, Luv.Stream.listen, and Luv.TCP.connect.

On libuv prior to 1.7.0, using ?domain causes this function to return Error `ENOSYS ("Function not implemented").

Feature check: Luv.Require.(has tcp_init_ex)

val open_ : t -> Os_fd.Socket.t -> (unit, Error.t) result

Wraps an existing socket in a libuv TCP stream.

Binds uv_tcp_open.

module Flag : sig ... end

Binds UV_NONBLOCK_PIPE.

val socketpair : 
  ?fst_flags:Flag.t list ->
  ?snd_flags:Flag.t list ->
  Sockaddr.Socket_type.t ->
  int ->
  (Os_fd.Socket.t * Os_fd.Socket.t, Error.t) result

Creates a pair of connected sockets.

Binds uv_socketpair. See socketpair(3p).

See Luv.Pipe.pipe for an explanation of the optional arguments.

The integer argument is the protocol number.

Requires Luv 0.5.7 and libuv 1.41.0.

Feature check: Luv.Require.(has socketpair)

val nodelay : t -> bool -> (unit, Error.t) result

Sets TCP_NODELAY.

Binds uv_tcp_nodelay.

val keepalive : t -> int option -> (unit, Error.t) result

Sets the TCP keepalive.

Binds uv_tcp_keepalive.

val simultaneous_accepts : t -> bool -> (unit, Error.t) result

Sets simultaneous accept.

Binds uv_tcp_simultaneous_accepts.

val bind : ?ipv6only:bool -> t -> Sockaddr.t -> (unit, Error.t) result

Assigns an address to the given TCP socket.

Binds uv_tcp_bind. See bind(3p).

val getsockname : t -> (Sockaddr.t, Error.t) result

Retrieves the address assigned to the given TCP socket.

Binds uv_tcp_getsockname. See getsockname(3p).

val getpeername : t -> (Sockaddr.t, Error.t) result

Retrieves the address of the given TCP socket's peer.

Binds uv_tcp_getpeername. See getpeername(3p).

val connect : t -> Sockaddr.t -> ((unit, Error.t) result -> unit) -> unit

Connects to a host.

Binds uv_tcp_connect. See connect(3p).

val close_reset : t -> ((unit, Error.t) result -> unit) -> unit

Resets the connection.

Binds uv_tcp_close_reset.
