InterlockedXor
InterlockedXor performs an atomic XOR operation on the specified LONG values. The function prevents more than one thread from using the same variable simultaneously.
Syntax
LONG InterlockedXor( LONG volatile *Destination, LONG 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.
For x64 architectures, this function is implemented using the compiler intrinsic. For the x86 architecture, use the _InterlockedXor compiler intrinsic directly.
This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
