Is it possible to control the number of elements read from queue

[alex.]

The data write into the queue follows the format of

(Data Length) + Data Block + (Data Length) + Data Block + (Data Length) + Data Block

When I read the data, need to read the Data Length first, then can read one Data Block.

Is there any function  in queue to do it?

Thanks

Hi turbot,

"Is there any function  in queue to do it?"

No, but there is the FOR loop to fetch datalength elements from the queue.

Or use the "flush queue" command the empty the queue - but you have to parse the element array afterwards...

You can only dequeue data in the same form as you enqueued them. So, if you enqueue 3 data blocks at once (in which form? String? Byte array?), you will only be able to extract all 3 blocks at once; you later need to parse the extracted data accordingly.
