Servers for one-to-one communication

type t

Type of a server

val addresses : t -> OBus_address.t list

addresses server returns all the addresses the server is listenning on. These addresses must be passed to clients so they can connect to server.

val shutdown : t -> unit Lwt.t

shutdown server shutdowns the given server. It terminates when all listeners (a server may listen on several addresses) have exited. If the server has already been shut down, it does nothing.

val make : 
  ?switch:Lwt_switch.t ->
  ?capabilities:OBus_auth.capability list ->
  ?mechanisms:OBus_auth.Server.mechanism list ->
  ?addresses:OBus_address.t list ->
  ?allow_anonymous:bool ->
  (t -> OBus_connection.t -> unit) ->
  t Lwt.t

make ?switch ?capabilities ?mechanisms ?addresses ?allow_anonymous f Creates a server which will listen on all of the given addresses.

parameter capabilites
is the set of the server's capabilities,

parameter mechanisms
is the list of authentication mechanisms supported by the server,

parameter addresses
default to { name = "unix"; args = [("tmpdir", "/tmp")],

parameter allow_anonymous
tell whether clients using anonymous authentication will be accepted. It defaults to false,

parameter capabilities
is the list of supported capabilities, it defaults to OBus_auth.capabilities

parameter f
is the callback which receive new clients. It takes as arguments the server and the connection for the client.
About errors:
- if no addresses are provided, it raises Invalid_argument,
- if an address is invalid, it raises Invalid_argument
- if listening fails for one of the addresses, it fails with the exception reported for that address
It succeeds if it can listen on at least one address.
When a new client connects, the server handles authentication of this client, then it creates a transport and the connection on top of this transport.
Note that connections passed to f are initially down. It is up to the user to set them up with OBus_connection.set_up.

val make_lowlevel : 
  ?switch:Lwt_switch.t ->
  ?capabilities:OBus_auth.capability list ->
  ?mechanisms:OBus_auth.Server.mechanism list ->
  ?addresses:OBus_address.t list ->
  ?allow_anonymous:bool ->
  (t -> OBus_transport.t -> unit) ->
  t Lwt.t

make_lowlevel is the same as make except that f receives only the transport, and no connection is created for this transport.
