AtomicInt -= ZZ -- atomic fetch and subtract

Synopsis

Operator: -=
Usage:

x -= y
Inputs:
- x, an atomic integer,
- y, an integer,
Outputs:
- an integer,

Description

The atomic integer x is decreased by y and its original value is returned. This operation occurs atomically and is thread safe.

i1 : x = new AtomicInt from 12

o1 = 12

o1 : AtomicInt

i2 : x -= 10

o2 = 12

i3 : x

o3 = 2

o3 : AtomicInt
