InterlockedXor16 function
Applies to: desktop apps | Metro style apps
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 __cdecl InterlockedXor16( __inout SHORT volatile *Destination, __in SHORT 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.
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.
