module Lock_file: Lock_file
val create : ?message:string ->
?close_on_exec:bool ->
?unlink_on_exit:bool -> string -> bool Import.Deferred.t
create ?message path tries to create a file at path containing the text message,
pid if none provided. It returns true on success, false on failure. Note: there is
no way to release the lock or the fd created inside! It will only be released when
the process dies.
val create_exn : ?message:string ->
?close_on_exec:bool ->
?unlink_on_exit:bool -> string -> unit Import.Deferred.t
create_exn ?message path is like create except that it throws an exception on
failure instead of returning a boolean value
val waiting_create : ?abort:unit Import.Deferred.t ->
?message:string ->
?close_on_exec:bool ->
?unlink_on_exit:bool -> string -> unit Import.Deferred.t
waiting_create path repeatedly tries to lock
path, becoming determined when
path
is locked or raising when
abort becomes determined. Similar to
Core.Lock_file.blocking_create.
val is_locked : string -> bool Import.Deferred.t
is_locked path returns true when the file at path exists and is locked, false
otherwise.
