InterlockedXor16 function (winnt.h)

Performs an atomic XOR operation on the specified SHORT values. The function prevents more than one thread from using the same variable simultaneously.

Syntax

SHORT InterlockedXor16(
  [in, out] SHORT volatile *Destination,
  [in]      SHORT          Value
);

Parameters

[in, out] Destination

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

[in] 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 the Intel Itanium-based systems and x64 architectures, this function is implemented using the compiler intrinsic. For the x86 architecture, use the _InterlockedXor16 compiler intrinsic directly.

This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.

Itanium-based systems:  For performance-critical applications, use InterlockedXor16Acquire or InterlockedXor16Release instead.

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