InterlockedXor function (wdm.h)

The InterlockedOr routine atomically computes a bitwise exclusive OR operation.

Syntax

C++

LONG InterlockedXor(
  [in, out] LONG volatile *Destination,
  [in]      LONG          Value
);

[in, out] Destination

A pointer to the variable to be exclusive ORed with Value. The result of the operation is stored in the variable.

[in] Value

Specifies the value to be exclusive ORed with the variable that is pointed to by Destination.

InterlockedXor returns the original value stored in the variable pointed to by Destination.

InterlockedXor atomically computes *Destination^=Value.

Interlocked operations cannot be used on non-cached memory.
