Performs an atomic XOR operation on the specified char values. The function prevents more than one thread from using the same variable simultaneously.
char InterlockedXor8( char volatile *Destination, char 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 original value of the Destination parameter.
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 the Intel Itanium-based systems and x64 architectures, this function is implemented using the compiler intrinsic. For the x86 architecture, use the _InterlockedXor8 compiler intrinsic directly.
This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
