An application-defined function that serves as the starting address for a timer callback or a registered wait callback. Specify this address when calling the CreateTimerQueueTimer, RegisterWaitForSingleObject function.
The WAITORTIMERCALLBACK type defines a pointer to this callback function. WaitOrTimerCallback is a placeholder for the application-defined function name.
Syntax
VOID CALLBACK WaitOrTimerCallback( __in PVOID lpParameter, __in BOOLEAN TimerOrWaitFired );
Parameters
- lpParameter [in]
-
The thread data passed to the function using a parameter of the CreateTimerQueueTimer or RegisterWaitForSingleObject function.
- TimerOrWaitFired [in]
-
If this parameter is TRUE, the wait timed out. If this parameter is FALSE, the wait event has been signaled. (This parameter is always TRUE for timer callbacks.)
Return value
This function does not return a value.
Remarks
This callback function must not call the TerminateThread function.
Examples
For an example that uses this callback function, see Using Timer Queues.
