Macro

#define LFDS711_QUEUE_UMM_GET_VALUE_FROM_ELEMENT( queue_umm_element )

Parameters

queue_umm_element

A struct lfds711_queue_umm_element. Not a pointer to it - the struct itself.

Return Value

Returns a void pointer, the value from the element.

Notes

The value set into a queue element is only guranteed to be visible to another logical core once the element has been dequeued by a thread running on that logical core.

So, for example, if there was a globally allocated queue element, where a thread on logical core A set a value and then enqueued the element to the queue, a thread on logical core B would only be guaranteed to see the value set by the other thread once it dequeues the element from the queue.

As with all liblfds macros, the macro operates on the structure itself, not a pointer to it.
