CloseThreadpoolTimer

Releases the specified timer object.

Syntax

void CloseThreadpoolTimer(
         PTP_TIMER pti
)  

Parameters

pti
Type: PTP_TIMERĀ 

[in, out] A TP_TIMER structure that defines the timer object. The CreateThreadpoolTimer function returns this structure.

Return value

None.

Remarks

The timer object is freed immediately if there are no outstanding callbacks; otherwise, the timer object is freed asynchronously after the outstanding callback functions complete.

In some cases, callback functions might run after CloseThreadpoolTimer has been called. To prevent this behavior:

  1. Call the SetThreadpoolTimer function with the pftDueTime parameter set to NULL and the msPeriod and msWindowLength parameters set to 0.
  2. Call the WaitForThreadpoolTimerCallbacks function.
  3. Call CloseThreadpoolTimer.

If there is a cleanup group associated with the timer object, it is not necessary to call this function; calling the CloseThreadpoolCleanupGroupMembers function releases the work, wait, and timer objects associated with the cleanup group.

Requirements

Header: Declared in threadpoolapiset.h.

Library: Use kernelx.lib.
