Hallo,  
I am used the FreeRTOS Queue in an application and want to be sure that:  
when l call xQueueReceive(p1,p2,p3…) then the received item is deleted from the Queue, so that i dont need to delete it myself.  
This is surely a nonsence question but l just want to be sure.🙂

Best regards

-Emeric

Items are queued by copy.&nbsp; If you want to queue a large data structure it is therefore best to queue a reference to the data rather than the data itself.

Whether a reference or the actual data, the item is copied to the queue storage area, then copied out again when you retrieve the item.&nbsp; You do not need to manage the queue storage area yourself - the queue handles this.&nbsp;

There is no dynamic memory allocation other than when the queue is originally created.
