Module type Af_common.S

A low-level socket interface, common to both Windows and Linux kernels

type t
type sockaddr

A socket address

val string_of_sockaddr : sockaddr -> string
val create : unit -> t

create () creates an unbound socket

val bind : t -> sockaddr -> unit

bind socket sockaddr binds socket to sockaddr

val listen : t -> int -> unit

listen socket queue_length sets the socket to listening mode with the given maximum queue length

val accept : t -> t * sockaddr

accept fd accepts a single connection

val connect : ?timeout_ms:int -> t -> sockaddr -> unit

connect ?timeout_ms fd sockaddr connects to a remote socket. On Windows the raw connect call can block forever if the server is not running when the call is executed (even if the server starts up afterwards) there is a default timeout of 300ms. On timeout this will raise Unix_error(Unix.ETIMEDOUT)

val writev : t -> Cstruct.t list -> int

Write a list of buffers

val read_into : t -> Cstruct.t -> int

Read into a buffer, returning the number of bytes written

val shutdown_read : t -> unit

Close the read half of the connection

val shutdown_write : t -> unit

Close the write half of the connection

val close : t -> unit

Close both halves of the connection
