InterlockedXor64

InterlockedXor64 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 InterlockedXor64(
        LONGLONG volatile *Destination,
        LONGLONG          Value
);

Parameters

Destination

A pointer to the first operand. This value will be replaced with the result of the operation.

Value

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.

Requirements

Minimum Supported Version	RTX64 3.1
Header	windows.h
