The handle of the queue being removed from the registry.
The queue registry has two purposes, both of which are associated with RTOS kernel aware debugging:
It allows a textual name to be associated with a queue for easy queue identification within a debugging GUI.
It contains the information required by a debugger to locate each registered queue and semaphore.
The queue registry has no purpose unless you are using a RTOS kernel aware debugger.
configQUEUE_REGISTRY_SIZE defines the maximum number of queues and semaphores that can be registered.
Only the queues and semaphores that you want to view using a RTOS kernel aware debugger need to be registered.

/* Create a queue big enough to hold 10 chars. */
xQueue = xQueueCreate( 10, sizeof( char ) );
/* We want this queue to be viewable in a RTOS kernel aware debugger,
so register it. */
vQueueAddToRegistry( xQueue, "AMeaningfulName" );
/* The queue gets used here. */
/* At some later time, the queue is going to be deleted, first
remove it from the registry. */
vQueueUnregisterQueue( xQueue );
vQueueDelete( xQueue );
