InterlockedXorAcquire function

Performs an atomic XOR operation on the specified LONG values. The operation is performed with acquire memory ordering semantics. The function prevents more than one thread from using the same variable simultaneously.

Syntax


LONG __cdecl InterlockedXorAcquire(
  _Inout_  LONG volatile *Destination,
  _In_     LONG 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 _InterlockedXor_acq.

This function is supported only on Itanium-based systems.

Note  Windows 8 does not support Itanium-based systems.

Note  This function is supported on Windows RT-based systems.
