- *\r
- * xLists can only store pointers to xListItems. Each xListItem contains a\r
- * numeric value (xItemValue). Most of the time the lists are sorted in\r
- * descending item value order.\r
- *\r
- * Lists are created already containing one list item. The value of this\r
- * item is the maximum possible that can be stored, it is therefore always at\r
- * the end of the list and acts as a marker. The list member pxHead always\r
- * points to this marker - even though it is at the tail of the list. This\r
- * is because the tail contains a wrap back pointer to the true head of\r
- * the list.\r
- *\r
- * In addition to it's value, each list item contains a pointer to the next\r
- * item in the list (pxNext), a pointer to the list it is in (pxContainer)\r
- * and a pointer to back to the object that contains it. These later two\r
- * pointers are included for efficiency of list manipulation. There is\r

- *\r
- * Counting semaphores are typically used for two things:\r
- *\r
- * 1) Counting events. \r
- *\r
- * In this usage scenario an event handler will 'give' a semaphore each time\r
- * an event occurs (incrementing the semaphore count value), and a handler \r
- * task will 'take' a semaphore each time it processes an event \r
- * (decrementing the semaphore count value). The count value is therefore \r
- * the difference between the number of events that have occurred and the \r
- * number that have been processed. In this case it is desirable for the \r
- * initial count value to be zero.\r
- *\r
- * 2) Resource management.\r
- *\r
- * In this usage scenario the count value indicates the number of resources\r
- * available. To obtain control of a resource a task must first obtain a \r
- * semaphore - decrementing the semaphore count value. When the count value\r
- * reaches zero there are no free resources. When a task finishes with the\r
- * resource it 'gives' the semaphore back - incrementing the semaphore count\r
- * value. In this case it is desirable for the initial count value to be\r
- * equal to the maximum count value, indicating that all resources are free.\r
- *\r
- * @param uxMaxCount The maximum count value that can be reached. When the \r

- * This function differs from vTaskDelay () in one important aspect: vTaskDelay () will\r

- *\r
- * Creates a new software timer instance. This allocates the storage required\r
- * by the new timer, initialises the new timers internal state, and returns a\r
- * handle by which the new timer can be referenced.\r
- *\r
- * Timers are created in the dormant state. The xTimerStart(), xTimerReset(),\r
- * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and\r
- * xTimerChangePeriodFromISR() API functions can all be used to transition a timer into the\r
- * active state.\r
- *\r
- * @param pcTimerName A text name that is assigned to the timer. This is done\r
- * purely to assist debugging. The kernel itself only ever references a timer by\r
- * its handle, and never by its name.\r
- *\r
- * @param xTimerPeriodInTicks The timer period. The time is defined in tick periods so\r
- * the constant portTICK_RATE_MS can be used to convert a time that has been\r
- * specified in milliseconds. For example, if the timer must expire after 100\r
- * ticks, then xTimerPeriodInTicks should be set to 100. Alternatively, if the timer\r
- * must expire after 500ms, then xPeriod can be set to ( 500 / portTICK_RATE_MS )\r
- * provided configTICK_RATE_HZ is less than or equal to 1000.\r
- *\r
- * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will\r
- * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter. If\r
- * uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and\r
- * enter the dormant state after it expires.\r
- *\r
- * @param pvTimerID An identifier that is assigned to the timer being created.\r
- * Typically this would be used in the timer callback function to identify which\r
- * timer expired when the same callback function is assigned to more than one\r
- * timer.\r
- *\r
- * @param pxCallbackFunction The function to call when the timer expires.\r
- * Callback functions must have the prototype defined by tmrTIMER_CALLBACK,\r
- * which is "void vCallbackFunction( xTimerHandle xTimer );".\r
- *\r
- * @return If the timer is successfully create then a handle to the newly\r
- * created timer is returned. If the timer cannot be created (because either\r
- * there is insufficient FreeRTOS heap remaining to allocate the timer\r
- * structures, or the timer period was set to 0) then 0 is returned.\r

-/**\r
- * portBASE_TYPE xTimerReset( xTimerHandle xTimer, portTickType xBlockTime );\r
- *\r
- * Timer functionality is provided by a timer service/daemon task. Many of the\r
- * public FreeRTOS timer API functions send commands to the timer service task\r
- * though a queue called the timer command queue. The timer command queue is\r
- * private to the kernel itself and is not directly accessible to application\r
- * code. The length of the timer command queue is set by the\r
- * configTIMER_QUEUE_LENGTH configuration constant.\r
- *\r
- * xTimerReset() re-starts a timer that was previously created using the\r
- * xTimerCreate() API function. If the timer had already been started and was\r
- * already in the active state, then xTimerReset() will cause the timer to\r
- * re-evaluate its expiry time so that it is relative to when xTimerReset() was\r
- * called. If the timer was in the dormant state then xTimerReset() has\r
- * equivalent functionality to the xTimerStart() API function.\r
- *\r
- * Resetting a timer ensures the timer is in the active state. If the timer\r
- * is not stopped, deleted, or reset in the mean time, the callback function\r
- * associated with the timer will get called 'n' ticks after xTimerReset() was\r
- * called, where 'n' is the timers defined period.\r
- *\r
- * It is valid to call xTimerReset() before the scheduler has been started, but\r
- * when this is done the timer will not actually start until the scheduler is\r
- * started, and the timers expiry time will be relative to when the scheduler is\r
- * started, not relative to when xTimerReset() was called.\r
- *\r
- * The configUSE_TIMERS configuration constant must be set to 1 for xTimerReset()\r
- * to be available.\r
- *\r
- * @param xTimer The handle of the timer being reset/started/restarted.\r
- *\r
- * @param xBlockTime Specifies the time, in ticks, that the calling task should\r
- * be held in the Blocked state to wait for the reset command to be successfully\r
- * sent to the timer command queue, should the queue already be full when\r
- * xTimerReset() was called. xBlockTime is ignored if xTimerReset() is called\r
- * before the scheduler is started.\r
- *\r
- * @return pdFAIL will be returned if the reset command could not be sent to\r
- * the timer command queue even after xBlockTime ticks had passed. pdPASS will\r
- * be returned if the command was successfully sent to the timer command queue.\r
- * When the command is actually processed will depend on the priority of the\r
- * timer service/daemon task relative to other tasks in the system, although the\r
- * timers expiry time is relative to when xTimerStart() is actually called. The\r
- * timer service/daemon task priority is set by the configTIMER_TASK_PRIORITY\r
- * configuration constant.\r
