Performs an atomic addition operation on the specified LONG values.
LONG InterlockedAdd( LONG volatile *Addend, LONG Value );
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 _InterlockedAdd.
This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
