InterlockedXor8Acquire function
Performs an atomic XOR operation on the specified char values. The operation is performed with acquire memory ordering semantics. The function prevents more than one thread from using the same variable simultaneously.
Syntax
char __cdecl InterlockedXor8Acquire(
_Inout_ char volatile *Destination,
_In_ char 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 _InterlockedXor8_acq.
Note This function is supported on Windows RT-based systems.
