This function atomically exchanges a pair of values. The function prevents more than one thread from using the same variable simultaneously.

If you are exchanging pointer values, this function supersedes InterlockedExchange.


PVOID InterlockedExchangePointer(
  PVOID* Target,
  PVOID Value
);

Target

[in, out] Pointer to the pointer to the value to exchange. The function sets the value to Value.

Value

[in] New value for Target.

Initial value pointed to by Target.

The interlocked functions provide a simple mechanism for synchronizing access to a variable that is shared by multiple threads. The threads of different processes can use this mechanism, if the variable is in shared memory.
