Ask a question about using of buffer

[sf_li]

I have read an element  for a  queue buffer, for   there are 10  element  in the queue,How can I get any element  in the queue.

There is a flush Queue function that will return all of the elements as an array. Then you can index this array. You can also take this array and put it back into the queue if you need to keep them. Queues aren't really made to pull items out of the middle.
