val create : 'a -> 'a tCreate a new protected value
val with_lock : 'a t -> ('a -> 'b) -> 'bwith_lock l f runs f x where x is the value protected with the lock l, in a critical section. If f x fails, with_lock l f fails too but the lock is released
module LockRef : sig ... endType allowing to manipulate the lock as a reference
with_lock_as_ref l f calls f with a reference-like object that allows to manipulate the value of l safely. The object passed to f must not escape the function call
val update : 'a t -> ('a -> 'a) -> unitupdate l f replaces the content x of l with f x, atomically
val get : 'a t -> 'aGet the value in the lock. The value that is returned isn't protected!
val set : 'a t -> 'a -> unitAtomically set the value
val incr : int t -> unitAtomically increment the value
val decr : int t -> unitAtomically decrement the value
