Would a one-shot timer cause a memory leak?

Question

I created a timer queue, then created some one-shot timer using the below code:

CreateTimerQueueTimer(
	&mut handle,
	self.timer_queue,
	Some(timer_runner),
	Some(ptr as _),
	duration.as_millis() as u32,
	0,
	WT_EXECUTEONLYONCE,
)

I have searched extensively, but none of the sources mention whether the timers will be automatically released if I do not call DeleteTimerQueueTimer, or if it would lead to a memory leak?

Answer 1

Hello,

Welcome to Microsoft Q&A!

Accordng to the Doc: CreateTimerQueueTimer function

The period of the timer, in milliseconds. If this parameter is zero, the timer is signaled once.

Although the one-shot timer is only signaled once, the timer is not automatically canceled. As far as I'm concerned, you need to call the DeleteTimerQueueTimer function to cancel a timer.

Thank you.
