Module Lock_file

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.

Nfs has analogs of functions in Core.Lock_file.Nfs; see there for documentation.
