Connection

type t

The type for connections.

val connect : endpoint:Funix.endpoint -> ( t option, string ) Stdlib.result

connect ~endpoint connects to a server offered on endpoint endpoint. None is returned if no server could be found.

val close : t -> unit

close c closes a connection. This never errors.

val fd : t -> Unix.file_descr

fd c is the file descriptor of c.

val send : t -> string -> ( bool, string ) Stdlib.result

send c s sends bytes s on c. The result is Ok false if the peer ends the connection.

val recv : t -> ( string option, string ) Stdlib.result

recv c receives bytes from c and is Ok None if the peer ends the connection.

type listener

The type for connection listeners.

val listener : 
  ?backlog:int ->
  endpoint:Funix.endpoint ->
  unit ->
  ( listener, string ) Stdlib.result

listener ~backlog ~endpoint () is a connection listener on endpoint. backlog is the argument for Unix.listen (defaults to 128).

val listen : listener -> ( t, string ) Stdlib.result

listen ~endpoint offers a connection on endpoint. Blocks until a client connects. The caller must eventually close the connection.

val close_listener : listener -> unit

close_listener l closes listener l.
