InterlockedAddNoFence function
Performs an atomic addition operation on the specified LONG values. The operation is performed atomically, but without using memory barriers.
Syntax
LONG __cdecl InterlockedAddNoFence(
_Inout_ LONG volatile *Addend,
_In_ LONG Value
);
Parameters
- Addend [in, out]
-
A pointer to the first operand. This value will be replaced with the result of the operation.
- Value [in]
-
The second operand.
Return value
The function returns the result of the operation.
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 _InterlockedAdd_nf.
This function generates no memory barriers (or fences) and does not guarantee that independent memory operations before or after it are completed in order.
