timer_delete - deletes previously created timer
timer_delete() deletes the specified timer, timer_id. The timer must have been created by a previous call to timer_create(2) and must not have been already deleted. The associated clock, allocated memory and timer overrun handlers are all released. If a required underlying alarm request was issued to the real-time clock, it is also canceled. After a successful timer_delete() call, the timer_t value is invalid and should not be reused.
timer_t[K] - ID of the timer to be deleted.
- K - Originated from kernel-space.

Example Use Case¶
timer_delete can be used to delete a timer, which was created by a previous call to timer_create(2), in order to prevent it from expiring.
If a call to timer_delete() fails, the timer may be left in an undefined state, which can cause the timer to be reused at a future point in time.
timer_create(2) - creates a timer, which can later be deleted by timer_delete().
