* The macro's crQUEUE_SEND_FROM_ISR() and crQUEUE_RECEIVE_FROM_ISR() are the

*
* crQUEUE_RECEIVE_FROM_ISR can only be called from an ISR to receive data

* placed. The size of the items the queue will hold was defined when the
* queue was created, so this many bytes will be copied from the queue into
* pvBuffer.

* @param pxCoRoutineWoken A co-routine may be blocked waiting for space to become

* Setting bits in an event group is not a deterministic operation because there

* set. FreeRTOS does not allow nondeterministic operations to be performed
* while interrupts are disabled, so protects event groups that are accessed
* from tasks by suspending the scheduler rather than disabling interrupts. As
* a result event groups cannot be accessed directly from an interrupt service
* routine. Therefore xEventGroupClearBitsFromISR() sends a message to the
* timer task to have the clear operation performed in the context of the timer
* task.
*
* @param xEventGroup The event group in which the bits are to be cleared.
*
* @param uxBitsToClear A bitwise value that indicates the bit or bits to clear.
* For example, to clear bit 3 only, set uxBitsToClear to 0x08. To clear bit 3
* and bit 0 set uxBitsToClear to 0x09.
*
* @return If the request to execute the function was posted successfully then
* pdPASS is returned, otherwise pdFALSE is returned. pdFALSE will be returned
* if the timer service queue was full.

* This is the list implementation used by the scheduler. While it is tailored
* heavily for the schedulers needs, it is also available for use by
* application code.
*
* list_ts can only store pointers to list_item_ts. Each ListItem_t contains a
* numeric value (xItemValue). Most of the time the lists are sorted in
* descending item value order.
*
* Lists are created already containing one list item. The value of this
* item is the maximum possible that can be stored, it is therefore always at
* the end of the list and acts as a marker. The list member pxHead always
* points to this marker - even though it is at the tail of the list. This
* is because the tail contains a wrap back pointer to the true head of
* the list.
*
* In addition to it's value, each list item contains a pointer to the next
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
* and a pointer to back to the object that contains it. These later two
* pointers are included for efficiency of list manipulation. There is
* effectively a two way link between the object containing the list item and
* the list item itself.

*
* Counting semaphores are typically used for two things:

* In this usage scenario an event handler will 'give' a semaphore each time
* an event occurs (incrementing the semaphore count value), and a handler
* task will 'take' a semaphore each time it processes an event
* (decrementing the semaphore count value). The count value is therefore
* the difference between the number of events that have occurred and the
* number that have been processed. In this case it is desirable for the
* initial count value to be zero.
*
* 2) Resource management.
*
* In this usage scenario the count value indicates the number of resources
* available. To obtain control of a resource a task must first obtain a
* semaphore - decrementing the semaphore count value. When the count value
* reaches zero there are no free resources. When a task finishes with the
* resource it 'gives' the semaphore back - incrementing the semaphore count
* value. In this case it is desirable for the initial count value to be
* equal to the maximum count value, indicating that all resources are free.
*
* @param uxMaxCount The maximum count value that can be reached. When the
* semaphore reaches this value it can no longer be 'given'.
*
* @param uxInitialCount The count value assigned to the semaphore when it is
* created.
*
* @return Handle to the created semaphore. Null if the semaphore could not be
* created.
*
* Example usage:
<pre>
SemaphoreHandle_t xSemaphore;
void vATask( void * pvParameters )
{
SemaphoreHandle_t xSemaphore = NULL;
// Semaphore cannot be used before a call to xSemaphoreCreateCounting().
// The max value to which the semaphore can count should be 10, and the
// initial value assigned to the count should be 0.
xSemaphore = xSemaphoreCreateCounting( 10, 0 );
if( xSemaphore != NULL )
{
// The semaphore was created successfully.
// The semaphore can now be used.
}
}

* This is a very simply blinky style example that can be generated
* automatically by the Xilinx SDK.
*
* The example generates a Tx task, an Rx task, and a queue. The Tx task
* simply uses the queue to send a value to the Rx task every 500ms. The Rx
* prints out a message each time it receives the value.
*
* The demo does little in the way of hardware configuration. Separate projects
* are provided that include comprehensive demos which demonstrate additional
* hardware configuration, and additional FreeRTOS features. See the following
* link for more details: http://www.freertos.org/a00090.html#XILINX
