InterlockedExchangePointer (Windows Embedded CE 6.0)
1/6/2010
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.
Syntax
PVOID InterlockedExchangePointer(
PVOID* Target,
PVOID Value
);
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 Value
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.
