Function `core.atomic.atomicFetchAdd`

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


						
				T atomicFetchAdd(MemoryOrder ms = MemoryOrder.seq, T)
				(
				

				  scope ref return T val,
				

				  size_t mod
				

				) pure nothrow @nogc @trusted
				

				if ((__traits(isIntegral, T) || is(T == U*, U)) && !is(T == shared));
				

				

				T atomicFetchAdd(MemoryOrder ms = MemoryOrder.seq, T)
				(
				

				  scope shared ref return 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.
