Performs an atomic addition operation on the specified LONGLONG values. The operation is performed with acquire memory ordering semantics.
LONGLONG __cdecl InterlockedAddAcquire64( _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.
The second operand.
The function returns the result of the operation.
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_acq.
Note This function is supported on Windows RT-based systems.
