       type 'a t

       An atomic (mutable) reference to a value of type 'a .

       val make : 'a -> 'a t

       Create an atomic reference.

       val get : 'a t -> 'a

       Get the current value of the atomic reference.

       val set : 'a t -> 'a -> unit

       Set a new value for the atomic reference.

       val exchange : 'a t -> 'a -> 'a

       Set a new value for the atomic reference, and return the current value.

       val compare_and_set : 'a t -> 'a -> 'a -> bool

       compare_and_set  r  seen  v  sets  the  new  value  of r to v only if its current value is
       physically equal to seen -- the comparison and the set occur atomically. Returns  true  if
       the comparison succeeded (so the set happened) and false otherwise.

       val fetch_and_add : int t -> int -> int

       fetch_and_add  r  n  atomically  increments  the value of r by n , and returns the current
       value (before the increment).

       val incr : int t -> unit

       incr r atomically increments the value of r by 1 .

       val decr : int t -> unit

       decr r atomically decrements the value of r by 1 .
