BaseType_t xTimerStop( TimerHandle_t xTimer,
TickType_t xBlockTime );
Software timer functionality is provided by a timer service/daemon task. Many of the
public FreeRTOS timer API functions send commands to the timer service task
through a queue called the timer command queue. The timer command queue is
private to the RTOS kernel itself and is not directly accessible to application
code. The length of the timer command queue is set by the
configTIMER_QUEUE_LENGTH configuration constant.
xTimerStop() stops a timer that was previously started using either of the
Stopping a timer ensures the timer is not in the active state.
The configUSE_TIMERS configuration constant must be set to 1 for xTimerStop()
to be available.
The handle of the timer being stopped.
Specifies the time, in ticks, that the calling task should
be held in the Blocked state to wait for the stop command to be successfully
sent to the timer command queue, should the queue already be full when
xTimerStop() was called. xBlockTime is ignored if xTimerStop() is called
before the RTOS scheduler is started.
pdFAIL will be returned if the stop command could not be sent to
the timer command queue even after xBlockTime ticks had passed. pdPASS will
be returned if the command was successfully sent to the timer command queue.
When the command is actually processed will depend on the priority of the
timer service/daemon task relative to other tasks in the system. The
timer service/daemon task priority is set by the configTIMER_TASK_PRIORITY
