Function core.atomic.atomicFetchSub
Atomically subtracts mod
from the value referenced by val
and returns the value val
held previously.
This operation is both lock-free and atomic.
T atomicFetchSub(MemoryOrder ms = MemoryOrder .seq, T)
(
ref T val,
size_t mod
) pure nothrow @nogc @trusted
if ((__traits(isIntegral, T) || is(T == U*, U)) && !is(T == shared));
T atomicFetchSub(MemoryOrder ms = MemoryOrder .seq, T)
(
shared ref T val,
size_t mod
) pure nothrow @nogc @trusted
if (__traits(isIntegral, T) || is(T == U*, U));
Parameters
Name | Description |
---|---|
val | Reference to the value to modify. |
mod | The value to subtract. |
Returns
The value held previously by val
