InterlockedExchangePointer (Windows CE 5.0)
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.
