Performs an atomic addition operation on the specified LONGLONG values. The operation is performed with release memory ordering semantics.

_Inout_ LONGLONG volatile *Addend,
_In_ LONGLONG Value
);
Addend [in, out]
A pointer to the first operand. This value will be replaced with the result of the operation.Value [in]
The second operand.

The interlocked functions provide a simple mechanism for synchronizing access to a variable that is shared by multiple threads. This function is atomic with respect to calls to other interlocked functions.
This function is implemented using a compiler intrinsic where possible. For more information, see the WinBase.h header file and _InterlockedAdd64_rel.
Note This function is supported on Windows RT-based systems.
