InterlockedXorNoFence function

Performs an atomic XOR operation on the specified LONG values. The operation is performed atomically, but without using memory barriers. The function prevents more than one thread from using the same variable simultaneously.

Syntax


LONG __cdecl InterlockedXorNoFence(
  _Inout_  LONG volatile *Value,
  _In_     LONG Mask
);

Parameters

Value [in, out]

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

Mask [in]

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 generates no memory barriers (or fences) and does not guarantee that independent memory operations before or after it are completed in order.

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

Requirements

Minimum supported client

Windows 8 [desktop apps only]

Minimum supported server

Windows Server 2012 [desktop apps only]

Header
