Parameters

module Log : Protocol_9p.S.LOG

Signature

include Protocol_9p.Client.S

type t

An established connection to a 9P server

val after_disconnect : t -> unit Lwt.t

A thread which wakes up when the connection to the server has been broken

val disconnect : t -> unit Lwt.t

Disconnect from the 9P server, but leave the underlying FLOW connected.

val create : 
  t ->
  string list ->
  string ->
  Protocol_9p__.Protocol_9p_types.FileMode.t ->
  (unit, [ `Msg of string ]) Result.result Lwt.t

create t path name perm creates a new empty file name inside path with * the given permissions.

val write : 
  t ->
  string list ->
  int64 ->
  Cstruct.t ->
  (unit, [ `Msg of string ]) Result.result Lwt.t

write t path offset buf writes buf to the file at path at offset offset

val read : 
  t ->
  string list ->
  int64 ->
  int32 ->
  (Cstruct.t list, [ `Msg of string ]) Result.result Lwt.t

read t path offset count returns a list of buffers containing count bytes from offset offset in the file given by path

val mkdir : 
  t ->
  string list ->
  string ->
  Protocol_9p__.Protocol_9p_types.FileMode.t ->
  (unit, [ `Msg of string ]) Result.result Lwt.t

mkdir t path name perm creates a new directory name inside path with * the given permissions.

val remove : t -> string list -> (unit, [ `Msg of string ]) Result.result Lwt.t

remove t path removes a file or directory from the filesystem.

val readdir : 
  t ->
  string list ->
  (Protocol_9p__.Protocol_9p_types.Stat.t list, [ `Msg of string ])
    Result.result
    Lwt.t

Return the contents of a named directory.

val stat : 
  t ->
  string list ->
  (Protocol_9p__.Protocol_9p_types.Stat.t, [ `Msg of string ]) Result.result
    Lwt.t

Return information about a named directory or named file.

module KV_RO : Mirage_kv_lwt.RO with type t = t

module LowLevel : sig ... end

The functions in this module are mapped directly onto individual 9P RPCs. The client must carefully respect the rules on managing fids and stay within the message size limits.

val walk_from_root : 
  t ->
  Protocol_9p__.Protocol_9p_types.Fid.t ->
  string list ->
  (Protocol_9p__.Protocol_9p_response.Walk.t, [ `Msg of string ]) Result.result
    Lwt.t

walk_from_root t is LowLevel.walk t root, where root is the internal Fid representing the root directory (which is not exposed by the API).

val with_fid : 
  t ->
  (Protocol_9p__.Protocol_9p_types.Fid.t ->
    ('a, [ `Msg of string ]) Result.result Lwt.t) ->
  ('a, [ `Msg of string ]) Result.result Lwt.t

with_fid t fn is the result of running fn x with a fresh Fid x, which is returned to the free pool when the thread finishes.

val connect : 
  string ->
  string ->
  ?msize:int32 ->
  ?username:string ->
  ?aname:string ->
  ?max_fids:int32 ->
  ?send_pings:bool ->
  unit ->
  t Protocol_9p.Error.t Lwt.t

connect proto address ?msize ?username ?aname () creates a 9P connection over proto to address with an optional maximum message size ?msize and optional ?username and authentication ?aname. max_fids is the maximal numbers of files concurrently opened by the client. If ?send_pings is true then regular "walk"s to / will be used to keep the connection alive-- this is useful over TCP connections where stateful middleboxes silently drop connections. Allowed combinations of proto and address are:

unix /path/to/file
tcp ip:port
