atomicFetchSub

core atomic

Atomically subtracts mod from the value referenced by val and returns the value val held previously. This operation is both lock-free and atomic.

  1. T atomicFetchSub(T val, size_t mod)
    pure nothrow @nogc @trusted
    T

    (
    MemoryOrder ms = MemoryOrder.seq
    T
    )
    (
    ref return scope T val
    ,
    size_t mod
    )
    if (
    (
    __traits(isIntegral, T) ||
    is(T == U*,
    U
    )
    )     &&
    !is(T == shared)
    )
  2. T atomicFetchSub(T val, size_t mod)

Parameters

val T

Reference to the value to modify.

mod size_t

The value to subtract.
