Module `Lock_file_async.Flock`

type t

Nfs has analogues of functions in Lock_file.Flock; see there for documentation. In addition to adding Deferreds, this module adds functions that operate in the Deferred.Or_error.t monad.

val lock_exn : 
  lock_path:string ->
  [ `Somebody_else_took_it | `We_took_it of t ] Async.Deferred.t

val lock : 
  lock_path:string ->
  [ `Somebody_else_took_it | `We_took_it of t ] Async.Deferred.Or_error.t

val unlock_exn : t -> unit Async.Deferred.t

val unlock : t -> unit Async.Deferred.Or_error.t

val wait_for_lock_exn : 
  ?abort:unit Async.Deferred.t ->
  lock_path:string ->
  unit ->
  t Async.Deferred.t

wait_for_lock_exn ?abort ~lock_path () Wait for the lock, giving up once abort becomes determined

val wait_for_lock : 
  ?abort:unit Async.Deferred.t ->
  lock_path:string ->
  unit ->
  t Async.Deferred.Or_error.t
