  _Inout_ LONGLONG volatile *Addend,

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.

This function is supported only on Itanium-based systems.
