vQueueUnregisterQueue
[Queue Management]

queue.h 

 void vQueueUnregisterQueue( 
                             QueueHandle_t xQueue, 
                           );

Removes a queue from the queue registry.

Parameters:
xQueue 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:
  1. It allows a textual name to be associated with a queue for easy queue identification within a debugging GUI.
  2. 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.

Example: 


void vAFunction( void )
{
QueueHandle_t xQueue;

    /* 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 );
}
