InterlockedAdd function (winnt.h)
Performs an atomic addition operation on the specified LONG values.
LONG InterlockedAdd( [in, out] LONG volatile *Addend, [in] LONG Value );
[in, out] Addend
A pointer to the first operand. This value will be replaced with the result of the operation.
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 _InterlockedAdd.
This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
