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 ); }
