InterlockedExchangePointer (Windows CE 5.0)

Send Feedback

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,PVOIDValue);

Parameters

  • 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.

Return Values

The function returns the initial value pointed to by Target.

Remarks

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.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Winbase.h.
Link Library: Coredll.lib.
