Module `Ambient_context_atomic.Atomic`Source

Atomic references.

Sourcetype 'a t = 'a Atomic.t

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

Sourceval make : 'a -> 'a t

Create an atomic reference.

Sourceval get : 'a t -> 'a

Get the current value of the atomic reference.

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

Set a new value for the atomic reference.

Sourceval exchange : 'a t -> 'a -> 'a

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

Sourceval 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.

Sourceval 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).

Sourceval incr : int t -> unit

incr r atomically increments the value of r by 1.

Sourceval decr : int t -> unit

decr r atomically decrements the value of r by 1.
