InterlockedXor64 function
Applies to: desktop apps | Metro style apps
Performs an atomic XOR operation on the specified LONGLONG values. The function prevents more than one thread from using the same variable simultaneously.
Syntax
LONGLONG __cdecl InterlockedXor64( __inout LONGLONG volatile *Destination, __in LONGLONG Value );
Parameters
- Destination [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 original value of the Destination parameter.
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 _InterlockedXor64.
This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
Itanium-based systems: For performance-critical applications, use InterlockedXor64Acquire or InterlockedXor64Release instead.
