InterlockedXor8Acquire function

Applies to: desktop apps | Metro style apps

Performs an atomic XOR operation on the specified char values. The operation is performed with acquire memory access 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.

This function is supported only on Itanium-based systems.

Requirements

Header

WinBase.h (include Windows.h)
