Remarks
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.
Note This function is supported on Windows RT-based systems.
Note Windows 8 does not support Itanium-based systems.
